Testaments to the Byzantine period remain with the ruined 15th-century Basilica of Agia Varvara , 2km from Voulgaro down a southeastern side road in tiny Latsiana, and the church of Agios Nikolaos , 2km beyond that in the hamlet of Mouri. The former was built on an ancient Greek temple site, while the latter has distinctive surviving frescoes. There are fantastic views from both sites.
