Near the summits of Mount Olympus at 2803 meter high, lies the chapel of the Prophet Elias (Profitis Ilias). The chapel is the highest ecclesiastical building of the Orthodox Church worldwide.Saint Dionysius, founder of the Monastery of the Holy Trinity (nowadays
known as Monastery Agios Dionysios), also founded the chapel of the
Prophet Elias in the 16th century. It was built on the ruins of an
ancient structure. Dionysus, who practiced an ascetic life, is said to
have lived in the church at times.
The chapel was built on the top of Mount Profitis Ilias; the main
building materials were the surrounding stones. The floor of the chapel
is covered with stone slabs, the outer walls are made of layered stones,
without further connecting material. Covered with stone slabs, the roof
is supported by a solid wooden construction to support the snow load.
An atrium is protected on the eastern and southern sides by a natural
stone wall, which has an entrance on the north side. The low entrance to
the chapel is on the south side of the building.
Inside hang
some icons; a small altar, framed by icons depicting saints of the
Orthodox Church, gives believers the opportunity to light a candle.
The closest mountain huts are the Apostolidis Hut (430 meters away) and the Christos Kakkalos Hut (around 600 meters away).
