The Church of Panagia Chalkeon (also known as the "Red Church"), an 11th-century Byzantine church, built AD 1028 by Christophoros Protospatharios (governor of Longobardia), his wife Maria, and their children. "Panagia Chalkeon" translates to "Our Lady of the Coppersmiths," referencing the coppersmith and blacksmith workshops historically (and currently) found in the surrounding neighborhood.
