If you explore the village market area in Skala Eressos, you'll find the remains of the early Christian Basilica of Agios Andreas. This paleochristian church dates from the first half of the 5th century and houses the sarcophagus of the patron saint of Eressos, Saint Andreas. The most stunning feature is a partially intact floor mosaic in what used to be the central aisle, which depicts a number of stylized animals.
