The nunnery of Agia Moni is located a couple of kilometers outside the town of Nafplion. The katholikon (= main church) is dating back to the middle of the 12th century. It is one of the most important churches of the middle Byzantine period in Greece. According to its foundation inscription the church was built with donations of the bishop of Argos and Nafplion, who had constructed it in the year of 1149.

The church is mainly of architectural interest as the murals and decorations have not survived. Apart from the church, the monastery complex consists of small chapels and housing and living quarters for the nuns, who still life here. The church is dedicated to Zoodochos (= “Source of life”). Just outside the nunnery one can find the monastic spring, which is famous for its water.
