Geography

The shape of Olympus was formed by rain and wind, which produced an isolated tower almost above the sea, which is only away from Litochoro. Olympus has many peaks and an almost circular shape. The mountain has a circumference of , an average diameter of , and of area.

Morphology

The complicated geological past of the region is obvious from the morphology of Olympus and its National Park. Features include deep gorges and lots of smooth peaks, many of them over , including Aghios Antonios (), Kalogeros (), Toumpa () and Profitis Ilias (). 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). It is Greece's highest peak. Then, on the right is Stefani (or Thronos Dios
hrone of Zeus, which presents the most impressive and steep peak of Olympus, with its last sharply rising 200 metres presenting the greatest challenge for climbers. Further south, Skolio ( second highest sub-peak – ) completes an arc of about 200 degrees, with its steep slopes forming on the west side, like a wall, an impressive precipitous amphitheatrical cavity, in depth and 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.
On the north side, between Stefani and Profitis Ilias, extends the Muses' Plateau, at , while further south, almost in the center of the massif, extends the
alpine tundra region of Bara, at an elevation of . 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, most of them lower than 2,000 m, small seasonal lakes and streams and a small river, Enipeas,
with its springs in the site Prionia and its estuary in the

Name and mythological associations

The origin of the name Όλυμπος (Olympos) is unknown.
One theory suggests that it is compounded of ''ou lyma (οὐ λύμα)'' and ''pous (πούς),'' meaning "pure foot", conforming to
Hesiod's description of the earth as a sort of footstool for heaven up from which rise the "Blessed Gods". According to
Robert S.P. Beekes the word is of
pre-Greek origin and he speculates that it originally
meant "mountain".
The word is also probably cognate with the
Mycenean Greek word 𐀄𐀬𐀠𐀊𐀍 (u-ru-pi-ja-jo) which is, most likely, a term used to describe people, or possibly an

the mountain was a hiding place and base of operations for

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 Muslim Albanian armatoloi who ravaged the countryside of Macedonia. However, Olympus's 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 (

Ancient and medieval sites

The whole region of Pieria's Olympus was declared an archaeological and historical site for the preservation of its monumental and historical character. Five kilometres 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's 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
In ancient Greek religion and Greek mythology, myth, Dionysus (; ) is the god of wine-making, orchards and fruit, vegetation, fertility, festivity, insanity, ritual madness, religious ecstasy, and theatre. He was also known as Bacchus ( or ; ...
(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 bishop's seat from the Byzantine period called
Louloudies and the Macedonian Tombs of
Katerini and
Korinos.
Christian monuments

In the Olympus region, there are also several Christian monuments, among them the
highest-elevation 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 (elevation 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 guerrilla den. Nowadays it has been partially restored and operates as a dependency of the
New Monastery of Dionysios, that is outside Litochoro. On Olympus's 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.

Archaeological evidence suggests that Mount Olympus was regularly visited in religious pilgrimages through antiquity and the early Middle Ages. For instance, ancient Greek pottery, coins, and evidence of sacrificial ashes estimated to be from 400 B.C. have been found on the summit.

in antiquity based on archaeological finds discovered in 1961. In the modern era, a series of explorers tried to study the mountain and 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 northern 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 until 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 Kakkalos, 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.

Climate

Generally speaking Olympus's climate can be described as
Mediterranean
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern ...
with continental influence. Its local variations are the result of the impact of the sea and the rugged terrain of the region. In the lower locations (Litochoro and the foothills) the climate is typically Mediterranean, i.e. hot and dry in the summer, but humid and cold in the winter. Higher it is more humid, warm and sometimes severe, with more intense meteorological phenomena; in these locations it often snows throughout winter, while rain and snow is not unusual even in the summer. The temperature varies in winter from −10 °C to 10 °C and in summer from 0 °C to 20 °C, while winds are an almost daily occurrence. Generally the temperature falls 1 °C per 200 m of elevation. As the elevation rises, meteorological phenomena are more intense and the changes in 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. The hottest month is August, while the 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's alpine region, recordings have been made in the 1960s in the highest-elevation

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. The 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.
Flora

The research of Olympus's plants started in 1836, when the French
botanist

Aucher-Éloy 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

, is of particular interest to botanists. The intense diversity of the landscape, the varying orientation of the slopes and their position in relation to the sea affect locally Olympus's 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's northeast side is densely forested, as it receives the most rainfall, while the southwest one has significantly sparser vegetation.
Flora zones
In Olympus there are generally four sequential flora zones, but due to the complex topography and variety of microclimates, these do not form an obvious clear sequence with elevation.
Mediterranean vegetation zone
A zone of evergreen broadleaf trees (
maquis) occurs between 300 and 500 metres elevation. Along with

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. Over 2,000 metres the forest becomes sparser, reaching to 2,750 metres, thus creating one of the highest forest

and 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.
Treeless high mountain 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 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.

Fauna

Olympus's fauna, which 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
roe deer, have disappeared. In ancient times there were

National Park
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 elevation is 600 metres and its peak, Mytikas, at 2,917.727 metres.
