Prodromou Monastery, Orthodox monastery in Arcadia, Greece

Prodromou Monastery is built on a rock above the gorge of the Tanos River, about 30 km west of Astros near the villages of Kastri and Perdikovrysi. Its buildings form a narrow courtyard with arches, stone stairs and covered balconies, and the katholikon stands on the second floor of the south wing, fitted into a hollow of the rock as an irregular Γ-shaped domed church.

Founded by tradition in the 8th century, the monastery is documented from 1126 by an inscription at its entrance. During the 1821 revolution it served as a base against the Ottomans, a military hospital and a refuge for civilians, and its monks fought at Dolyana and Vervena. In 1826 Ibrahim Pasha besieged it twice without success.

The katholikon, on the upper floor of the south wing, keeps wall paintings of the 18th century by the hieromonk Ieremias of Nafplio, and its carved wooden iconostasis holds 18th-century icons. The monastery celebrates on 6 and 14 September. A narrow passage beside the church leads into a cave whose end is unknown; some believe it reaches the Malevis Monastery.

Beside the katholikon a narrow passage leads into a cave whose far end is unknown; some believe it connects to the Malevis Monastery. The katholikon itself is a domed church built in an irregular Γ shape to fit a hollow in the rock, with 18th-century wall paintings by the Nafplio hieromonk Jeremiah.
