Mount Olympus (/
Olympus was notable in Greek mythology as the home of the Greek gods, on Mytikas peak. Mount Olympus is also noted for its rich flora. It has been a National Park, the first in Greece, since 1938. It is also a World Biosphere Reserve.
Every year, thousands of people visit Olympus to admire its fauna and flora, tour its slopes, and reach its peaks. Organized mountain refuges and various mountaineering and climbing routes are available to visitors who want to explore it. The usual starting point is the town of Litochoro, on the eastern foothills of the mountain, 100 km from Thessaloniki, where, at the beginning of every summer, the Olympus Marathon terminates.
The shape of Olympus was formed by rain and wind, which produced an isolated tower almost 3,000 metres (9,800 ft) above the sea, which is only 18 kilometres (11 mi) away at Litochoro. Olympus has many peaks and an almost circular shape. The mountain has a circumference of 150 kilometres (93 mi), an average diameter of 26 kilometres (16 mi), and 500 square kilometres (190 sq mi) of area. To the northwest lies the Vlach village of Kokkinoplou. The Makryrema stream separates Olympus from the massif of Voulgara. The villages Petra, Vrontou and Dion lie to the northwest, while on the eastern side there is the town of Litochoro, where Enipeas bisects the massif of Olympus. On its southeastern side, the Ziliana gorge divides Mount Olympus from Kato Olympos (Lower Olympus), while on its southwestern foothills, there are the villages Sykaminea and Karya. The Agia Triada Sparmou Monastery and the village Pythion lie to the west.
Olympus' dry foothills, known as the Xirokampi, are covered in chaparral and provides habitat for animals such as wild boar. Further east, the plain of Dion is fertile and watered by the streams which originate on Olympus.
Mount Olympus is formed of sedimentary rock laid down 200 million years ago in a shallow sea. Various geological events that followed caused the emergence of the whole region and the sea. Around one million years ago glaciers covered Olympus and created its plateaus and depressions. With the temperature rise that followed, the ice melted and the streams that were created swept away large quantities of crushed rock in the lowest places, forming the alluvial fans, that spread out all over the region from the foothills of the mountain to the sea. The Geological Museum of Mount Olympus, located in Leptokarya, provides detailed information about the geological structure of the mountain.
The complicated geological past of the region is obvious from the morphology of Olympus and its National Park. Features include deep gorges and dozens of smooth peaks, many of them in altitude of more than 2,000 metres (6,600 ft), including Aghios Antonios (2,815 metres (9,236 ft)), Kalogeros (2,700 metres (8,900 ft)), Toumpa (2,801 metres (9,190 ft)) and Profitis Ilias (2,803 metres (9,196 ft)). However, it is the central, almost vertical, rocky peaks, that impress the visitor. Over the town of Litochoro, on the horizon, the relief of the mountain displays an apparent V, between two peaks of almost equal height. The left limb is the peak named Mytikas (or Pantheon – 2,918 metres (9,573 ft)). It is Greece's highest peak. Then, on the right is Stefani (or Thronos Dios [Throne of Zeus – 2,902 metres (9,521 ft)]), which presents the most impressive and steep peak of Olympus, with its last sharply rising 200 meters presenting the greatest challenge for climbers. Further south, Skolio (40°04′58″N 22°21′26″E / 40.0829°N 22.3571°E second highest peak – 2,912 metres (9,554 ft)) completes an arc of about 200 degrees, with its steep slopes forming on the west side, like a wall, an impressive precipitous amphitheatrical cavity, 700 metres (2,300 ft) in depth and 1,000 metres (3,300 ft) in circumference, the 'Megala Kazania'. On the east side of the high peaks the steep slopes form zone like parallel folds, the 'Zonaria'. Even narrower and steeper scorings, the 'Loukia', lead to the peak.
Οn the north side, between Stefani and Profitis Ilias, extends the Muses' Plateau, at 2,550 metres (8,370 ft), while further south, almost in the center of the massif, extends the alpine tundra region of Bara, at an altitude of 2,350 metres (7,710 ft). Olympus has numerous ravines and gullies. Most distinguishable of the ravines are those of Mavrologos-Enipeas (14 km) and Mavratzas-Sparmos (13 km) near Bara and 'cut' the massif in two oval portions. On the southern foothills the great gorge of Ziliana, 13 km long, consists of a natural limit that separates the mountain from Lower Olympus. There are also many precipices and a number of caves, even nowadays unexplored. The form and layout of the rocks favor the emergence of numerous springs, mainly lower than 2,000 m, of small seasonal lakes and streams and of a small river, Enipeas, with its springs in the site Prionia and its estuary in the Aegean Sea.
Name and mythological associations
The origin of the name Όλυμπος Olumpos is unknown and usually considered of "pre-Greek" origin. In Homeric Greek (Odyssey 6.42), the variant Οὔλυμπος Oulumpos occurs, conceived of as the seat of the gods (and not identified with any specific peak). Homer (Iliad 5.754, Odyssey 20.103) also appears to be using οὔλυμπος as a common noun, as a synonym of οὐρανός ouranos "sky". Mt Olympus was historically also known as Mount Belus, after Iliad 1.591, where the seat of the gods is referred to as βηλ[ός] θεσπεσίο[ς] "heavenly threshold".
In Ancient Greek religion and mythology, "Olympus" was the name of the home of the Twelve Olympian gods of the ancient Greek world. This was conceived of as a lofty mountaintop, and in all regions settled by Greek tribes, the highest local elevation tended to be so named; among the numerous peaks called Olumpos in antiquity are mountains in Mysia, Laconia, Lycia, Cyprus, Attica, Euboea, Ionia and Lesbos, and others. Thessalian Olympus is the highest peak in any territory with Greek settlement and came to be seen as the "Pan-Hellenic" representative of the mythological seat of the gods, by at least the 5th century BC, as Herodotus (1.56) identifies Olympus as the peak in Thessaly.
In antiquity, the Olympus massif forms the border between Thessaly and Macedon. The history of the surrounding area is consequently of interest in the context of the Rise of Macedon, the Chremonidean War and the Macedonian Wars during the 4th to 2nd centuries BC. In the period of the Ottoman Empire the mountain was a hiding place and base of operations for klephts and armatoloi.
In Olympus, the second armatoliki was founded, led by Kara Michalis in 1489. The action of the klephts in Olympus led the Turks to visit their outrage on the klephts' ally-village of Milia (in the late 17th century), which they destroyed. In that period Livadi in Olympus became the seat of the armatoliki of Olympus and Western Macedonia, with their first renowned commander Panos Zidros. In the 18th century the Turks had to replace the armatoloi (who very often joined the klephts) with Moslem Albanian armatoloi who ravaged the countryside of Macedonia. However, Olympus' armatoloi, even after their capitulation to Ali Pasha, never ceased fighting on land and at sea. Among them who were active there and in nearby regions were Nikotsaras, Giorgakis Olympios and the legendary family of Lazaioi. In the early 20th century, even for some time after the liberation from the Ottoman Empire (1912), robbers were active in the region – the best known of them the notorious Giagoulas, while during the German invasion in 1941 the Greek army fought significant battles along with units of New Zealanders and Australians. During the German Occupation (1941–1944) the mountain was one of the centers of the Greek Resistance, while a little later the Greek Civil War (1946–49) started there, in Litochoro.
Ancient and medieval sites
The whole region of Pieria's Olympus was declared archaeological and historical site for the preservation of its monumental and historical character. Five km away from the sea is Dion, sacred city of the ancient Macedons, dedicated to Zeus and the Twelve Olympians. Its prosperity lasted from the 5th century BC to the 5th century AD The excavations, continuing since 1928, have revealed numerous findings of the Macedonian, the Hellenistic and the Roman period. Currently there is a unique archaeological park of 200 hectares, with the ancient town and the sacred places of worship, outside its walls. Many statues and other invaluable items are kept in the nearby Dion's archaeological museum. Pimblia and Leivithra, two other towns in Olympus' region, are related to Orpheus and the "Orphic" mysteries. According to a tradition Orpheus, son of Apollo and Calliope (one of the Muses), taught here the mystic ceremonies of worship of Dionysus (also known as Bacchus). By the sea, in a strategic position, at Macedonia's gates is located Platamon Castle, built between 7th and 10th century AD in the ancient town of Heracleia. To the north the ancient Pydna is located. Here, in 168 BC, the decisive battle between the Macedonians and the Romans took place. Between Pydna and Mount Olympus are a fortified bishops seat from the Byzantine period called Louloudies and the Macedonian Tombs of Katerini and Korinos.
In the Olympus region, there are also several Christian monuments, among them the highest-altitude chapel of Orthodox Christianity, dedicated to Prophet Elias, in Greek tradition associated with mountaintops, on the summit of the same name (Προφήτης Ηλίας Profitis Ilias), at 2,803 m. It was built in the 16th century by Saint Dionysios of Olympus, who also founded the most significant monastery in the region. The Old Monastery of Dionysios (altitude 820 m) lies in Enipeas' gorge and is accessible by car from Litochoro. It was looted and burned by the Ottomans and in 1943 it was destroyed by the German invaders, who suspected it was a guerilla den. Nowadays it has been partially restored and operates as a dependency of the New Monastery of Dionysios, that is outside Litochoro. On Olympus' southern foot, in a dominant position (820 m) in Ziliana gorge, there is the Kanalon Monastery, 8 km away from Karya. It was founded in 1055 by the monks Damianos and Joakim and since 2001 it has been restored and operates as a convent. Further west, in the edge of Mavratza stream, at 1,020 m, there is the Agia Triada Sparmou Monastery, that flourished in the early 18th century, possessed great property and assisted to establish the famous Tsaritsani' school. It was abandoned in 1932, but in 2000 it was completely renovated and reopened as a male monastery, affiliated to Elassona's diocese.
The third highest peak of Mt Olympus, called Agios Antonios (Άγιος Αντώνιος "Saint Anthony", 40°04′04″N 22°21′04″E / 40.0677°N 22.3511°E, 2,817 m), is known to have been the site of a sanctuary of Zeus in antiquity based on archaeological finds discovered in 1961. In the modern era, a series of explorers tried to study the mountain and to tried to reach its summit. Examples include the French archaeologist Leon Heuzey (1855), the German explorer Heinrich Barth (1862), and the German engineer Edward Richter. Richter tried to reach the summit in 1911 but was abducted by klephts, who also killed the Ottoman gendarmes that accompanied him.
It was just one year after the liberation of Greece from Ottoman rule, on 2 August 1913, that the summit of Olympus was finally reached. The Swiss Frédéric Boissonnas and Daniel Baud-Bovy, aided by a hunter of wild goats from Litochoro, Christos Kakkalos, were the first to reach Greece's highest peak. Kakkalos, who had much experience climbing Olympus, was the first of the three to climb Mytikas. Afterwards, and till his death in 1976, he was the official guide on Olympus. In 1921, he and Marcel Kurz reached the second highest summit of Olympus, Stefani. Based on these explorations, Kurz in 1923 edited Le Mont Olympe, a book that includes the first detailed map of the summits. In 1928, the painter Vasilis Ithakisios climbed Olympus together with Kakalos, reaching a cave that he named Shelter of the Muses, and he spent many summers painting views of the mountain. Olympus was later photographed and mapped in detail by others, and a series of successful climbs and winter ascents of the steepest summits in difficult weather conditions took place.
Climbing Mount Olympus is a non-technical hike, except for the final section from the Skala summit to the Mytikas peak, which is a YDS class 3 rock scramble. It is estimated that 10,000 people climb Mount Olympus each year, most of them reaching only the Skolio summit. Most climbs of Mount Olympus start from the town of Litochoro, which took the name City of Gods because of its location at the foot of the mountain. From there a road goes to Prionia, where the hike begins at the bottom of the mountain.
Generally speaking Olympus' climate can be described as one of mediterranean type with continental influence. Its local variations is the result of the impact of the sea and the rugged relief of the region. In the lower locations (Litochoro and the foothills) the climate is typically mediterranean, i.e. hot and dry in the summer, while humid and cold in the winter. Higher it is more humid and severe, with more intense phenomena; in these locations it often snows all over the winter, while raining and snowing is not unusual, even in the summer. The temperature varies in the winter from -10 °C to 10 °C and in the summer from 0 °C to 20 °C, while winds are an almost everyday occurrence. Generally the temperature falls 1 °C per 200 m of altitude. As the altitude rises, the phenomena are more intense and the variations of temperature and humidity are often sudden.
The coastal northeast slopes of Olympus receive more rain than the continental northwest, so, as a result, there is a clear difference in vegetation, being more abundant in the first of them. Hottest month is August, while coldest is February.
The mountain's highest zone, over 2,000 metres, is snowcapped for about nine months (September to May). In some places the winds gather snow, 8–10 metres thick, ('anemosouria' in Greek), while in some deep ravines the snow is maintained all over the year (everlasting snow). For this Olympus' alpine region, recordings have been made in the 1960s in the highest-altitude weather station in Greece, that was established on the summit of Aghios Antonios (2,815 m), providing a number of interesting data for the mountain's climate. Τhe average temperature is -5 °C in winter and 10 °C in summer. The average annual precipitation heights vary from 149 cm at Prionia (1,100 m) to 170 cm at Aghios Antonios, about half of them rainfall and hailstorms in summer and the rest snowfall in winter. The weather may change several times in the same day. In summer rainfalls are frequent, commonly as evening thunderstorms, many times accompanied by hail and strong winds. However water springs over 2,000 metres are scarce and visitors should ensure that they have always water and of course the necessary clothing for any weather conditions.
The research of Olympus' plants started in 1836, when the French botanist Αυcher - Εlογ studied them. According to this and later studies, the National Park of Olympus is considered one of the richest flora regions in Greece, with about 1,700 species and subspecies, that represent some 25% of Greek flora. Of them 187 are characterized as significant, 56 are Greek endemic and of them 23 are local endemic, i.e. they can be found only in Olympus, and 16 are rare in Greece or/and have there the limits of their spread within Northern Greece.
An important book about the plants and flowers, from the beach of the agean sea up to the upper regions, of Mount Olympus was written in 1980 by the Swedish botanist Arne Strid.
Most of those found in lower altitude are the common Mediterranean and central European species. Jankaea heldreichii, a plant relic of the Ice age, is of particular interest for the botanists. Τhe intense diversity of the landscape, the varying orientation of the slopes and their position in relation to the sea affect locally Olympus' climate and so a local microclimate prevails, combined with the geological background and the soil favor the growth of particular vegetation types and biotopes. Generally Olympus' northeast side is densely forested, as it receives the most rainfall, while the southwest one has significantly sparser vegetation. Moreover, there is a clear sequence of the vegetation zones in accordance to altitude, in Olympus there is no such a regularity. It is due to the great microclimate variety, caused by the region's landscape.
In Olympus there are generally four sequent flora zones, but not clearly separated:
Mediterranean vegetation zone
In the altitude between 300 and 500 metres occurs the evergreen broadleaf trees' zone (maquis). Along with oak (Quercus ilex) and Greek strawberry tree there occur kermes oak, strawberry tree, Phillyrea latifolia, bay laurel, cedar and others. Of the deciduous species most common are flaxinus ulmus, Montpellier maple, Judas tree, terebinth, Cotinus coggygria and others.
Forest zone of beech, fir and mountain coniferous
The evergreen broadleaf trees' zone is gradually replaced by ecosystems of European black pine, that forms compact clusters, with no intermediate zone of deciduous oaks, although trees of these species occur sporadically within clusters of black pine. On the northern slopes of Xirolakos valley, at altitude between 600 and 700 metres, there is a high forest of downy oak of about 120 hectares.
Τhe black pine dominates on the eastern and northern side of the mountain, between 500 and 1,700 metres. In this zone there is also hybrid fir in small groups and scrubs or small clumps, particularly in the lower region and in the sites Naoumi (west) and Stalamatia and Polykastro (east), where it is mixed with black pine and Bosnian pine. In this zone there is also beech. While in the neighboring mountains Pierians and Ossa it creates an extended vegetation zone, in Olympus it is restricted to small clusters, appearing as islets, mainly in more humid locations and the best soils. A particularly rich variety of trees and shrubs is found in Enipeas' gorge. One can see there elm, cherry plum, European yew, hazel, holly, cornus mas, manna ash, maple and a considerable variety of herbaceous plants. Gorges and ravines are covered by oriental planes, willows, black alders and riverside greenery.
Boreal coniferous zone
Typical species of this zone is Bosnian pine. This rare kind of pine occurs sporadically higher than 1,000 metres and gradually replaces the black pine, while over 1,400 metres it creates an almost unmixed forest. Οver 2,000 metres the forest becomes sparser, reaching to 2,750 metres, thus creating the highest forest limit (highest limit of forest growth) in the Balkans, or even in Europe. Another feature of this zone is that over 2,500 metres the trees appear in a crawling form. The region, where Bosnian pine grows, is mostly dry and its slopes are rocky. There are no springs or water streams. The vegetation growing there is adapted to specific local conditions and represented by typical shrubs, graminaceous, chasmophytes etc., while the flora includes many endemic species of the Balkans.
No forest high mountains' zone (Alpine tundra)
Beyond Bosnian pine's zone follows an extensive zone, without trees, with alpine meadows, consisted by a mosaic of grassland ecosystems, depending on the topography, the slope and the orientation of the ground. In general, this alpine flora with more than 150 plant species, contains snow accumulation meadows, grassy swamps, alpine scree and rock crevices. On the meadows, the rocks and the steep slopes live most of the endemic Olympus' plants, among them some of the most beautiful wildflowers in Greece. Half of them are found only in the Balkans and 23 only in Olympus and nowhere else.
Local endemic plants
Achillea ambrosiaca, Alyssum handelii, Asprerula muscosa, Aubrieta thessala, Campanula oreadum, Carum adamovicii, Centaurea incompleta, Centaurea litochorea, Centaurea transiens, Cerastrium theophrasti, Coincla nivalis, Erysimum olympicum, Festuca olympica, Genista sakellariadis, Jankaea heldreichii, Ligusticum olympicum, Melampyrus ciliatum, Ophrys helenae (Ophrys sphegodes subsp. helenae), Poa thessala, Potentilla deorum, Rynchosinapis nivalis, Silene dionysii, Silene oligantha, Veronica thessalica, Viola striis-notata, Viola pseudograeca.
Οlympus' fauna, that has not been systematically studied so far, includes considerable variety and is marked by important, rare and endangered species. Large mammals, that lived formerly in the region, like deer, have disappeared. In ancient times there were lions (Pausanias), while at least until the 16th century there were bears (Life of St. Dionysios the Later).
There have been recorded 32 species of mammals, including wild goat (Rυρicapra rupicapra balcanica), roe deer (Capreolus capreolus), wild boar (Sus scrofa), wildcat (Felis sylvestris), beech marten (Martes foina), red fox (vulpes vulpes) and red squirrel (Sciurus vulgaris). There have also been detected 108 species of birds (like sparrowhawk, cinereous vulture, rock partridge, white stork, rock dove, European robin, lanner falcon, peregrine falcon, tree falcon, golden eagle, short-toed snake eagle, booted eagle and hoopoe). Many of them, particularly the birds of prey, are scarce. In addition there are the common reptiles of Greek fauna (22 species like snakes, turtles, lizards, etc.) and some amphibians (8 species) in streams and seasonal ponds, as well as a great variety of insects, particularly butterflies.
Greece's highest mountain, dwelling of the Twelve Gods of antiquity, has been the first region in the country to be applied specific protective rules, by its declaration as a National Park in 1938. The aim of this declaration was "...the preservation in perpetuity of the natural environment of the region, i.e. of wild flora, fauna and natural landscape, as well as its cultural and other values...". In addition the declaration has aimed promoting scientific research along with environmental education for the public and tourist development in the region. Specific laws prohibit all forms of exploitation on the eastern side of the mountain in an area of about 4,000 hectares, that is the core of the Park. A wider region, around this core, has been designated "peripheral zone of the National Park", so that its managing and exploitation to be done so as not to adversely affect the core's protection. At present, the park has been expanded to 24,000 hectares. Administratively it belongs to Pieria's and Larissa's Prefectures and specifically to the municipalities Diou-Olympou and Katerinis (Pieria) and Τempon and Elassonas (Larissa). Its lowest altitude is 600 metres and its peak, Mytikas, at 2,918 metres. In 1981 UNESCO proclaimed Olympus "Biosphere Reserve". European Union has listed Olympus in the "Significant for Birdlife Regions of European Union". It is also registered in the list of Natura 2000 European Network as a special protection area and a site of community interest.
In June 2016 the Olympus National Park Information Center, located at Litochoro, opened its gates. It informs their visitors about geologie, archaeological sites, mythology, monasteries, plants, animals and other subjects affecting Mount Olympus. Hikers will find help from professional rangers, a guide provides tours for groups in the mountain area.
