Prodromou Monastery, Greek Orthodox monastery in Stemnitsa, Greece

Prodromou Monastery is built into a rock cavity on the eastern bank of the Lousios Gorge, at 520 metres altitude and about 200 metres above the river bed, 8 km west of Stemnitsa. It consists of two buildings: the original one to the east and a newer one to the north dating from 1860. The oldest church, just 2.25 by 4.90 metres, stands against the rock wall, and its iconostasis sits at roughly 45 degrees to the nave because of the lack of space.

Founded by monks who had lived in nearby hermitages since the 12th century, the monastery took shape when these communities merged around the late 16th century. Tradition credits its foundation in 1167 to Emperor Manuel Komnenos, but reliable sources place the present monastery in the 16th century. The oldest church, just 2.25 by 4.90 metres, was built against the rock wall, and its frescoes were painted directly on the rock at the end of the 16th or beginning of the 17th century.

The monastery is dedicated to Saint John the Baptist, called Prodromos, "the Forerunner", in Orthodox tradition. Its oldest church measures only 2.25 by 4.90 metres and stands against the rock wall; the iconostasis sits at roughly 45 degrees to the nave because there was no room for another arrangement. Frescoes were painted directly on the rock at the end of the 16th and start of the 17th century.

Visitors should park in Stemnitsa and walk roughly 600 meters along a hiking trail to reach the monastery entrance. The path is clearly marked and leads directly to an old plane tree that stands at the gates.

The monastery gate still bears bullet holes from a failed siege attempt in 1779, serving as a physical reminder of conflicts the site endured. These marks remain visible today as evidence of its troubled past.
