Isova is the site of a ruined Frankish monastery near the modern village of Trypiti (formerly Bitzibardi) in the western Peloponnese, Greece. The church of Notre Dame at Isova, built in the first half of the 13th century, is among the best surviving examples of Gothic architecture in the Peloponnese, along with the church of Saint Sophia at Andravida and the monastery of Zaraka at Stymphalia.
