The metropolis of Didymoteichon
The metropolitan church of Agios Athanasios in the castle was renovated in 1834 as we can see from the marble inscription at the entrance. It is a three-aisled wooden-roofed basilica. The church is built on a church of the Palaeologan era, mid 13th - mid 15th century. Next to the northern wall of the church, the ruins of a monastery can be seen.
Interesting is the carved wooden iconostasis with icons of saints and monochrome landscape paintings in the lower zone.
