The Monastery of Saint Mary in Pojan is located within the complex of the Apollonia Archaeological Park. It was built in the 13th century CE. By the end of antiquity, Apollonia was largely depopulated, hosting a small Christian community that built this monastery on a hill, probably the site of the old city. Byzantine Emperor Andronicus Paleologus the Second reconstructed it. The chapel was built in the Byzantine style. The Monastery of Saint Mary is one of the most beautiful structures of this kind in Albania.
