The Kaisariani Monastery is an Eastern Orthodox monastery built on the north side of Mount Hymettus, near Athens, Greece. One of the oldest monasteries in Attica is the Holy Monastery of Kaisariani located on the slopes of a hill, on the northern side of Mount Hymettus, at an altitude of 350 meters. The medieval church was founded during the Byzantine times, in the late 11th century and it was dedicated to the Presentation of the virgin in the Temple. According to several historical sources, the monastery was built on the remains of a Roman sanctuary.

Kaisariani Monastery was built over the ruins of a Roman temple. Today, four columns of the ancient temple survive and support the dome of the monastery’s church. The walled complex has a central court surrounded by a kitchen and dining rooms, the monks’ cells, and a bathhouse. The monastery was a major cultural center during the years of economic prosperity at the end of the 12th century and beginning of the 13th century AD. The church of the monastery was dedicated to the Presentation of the Virgin and is built in the shape of the Greek cross. It was used briefly as a convent after the War of Independence until 1855. It was restored in 1956.
