Simonopetra monastery, Orthodox monastery on Mount Athos, Greece

Simonopetra is an Orthodox monastery built on a rocky outcrop along the Mount Athos peninsula that rises sharply above the sea. The structure spans multiple levels and uses the natural rock formation as its foundation.

The monastery was founded in the 13th century after a monk experienced a religious vision at the site and chose to settle there. Following several fires over the centuries, it was rebuilt multiple times and developed into its present form.

The monastery celebrates its patronal feast on 25 December for the Nativity of Christ, and on 28 December for founder Saint Simon the Myrrh-bearer. The left hand of Saint Mary Magdalene, venerated as co-founder, is kept in the chapel of Saint Mary Magdalene on the first floor of the eastern wing. Its choir is known for Byzantine chant recordings, notably Agni Parthene (1990).

Access to the monastery is restricted and requires special permits obtained well in advance. The journey typically involves a boat ride from a nearby port, and visitors should prepare for longer wait times and basic conditions.

The monastery's choir has earned recognition among Byzantine music specialists; its recordings include "Agni Parthene" (1990), the hymn that brought the choir and monastery wide renown. The brotherhood was nearly abandoned in the mid-20th century until Emilianos (Vafidis) and his monks arrived from Great Meteoron in 1973.
