Churches, houses and arched graves have been kept in remarkable condition in some cases up to roof height. In Vathi there are ruins of thirteen Paleo-Christian Churches. These are: Agia Sophia (Saint Sophia), Anastasi (Resurrection), Agios Georgios (Saint George), Agia Irini (Saint Irene), Vasiliki Ikopedou Chalkiti, Unknown Church, Paleopanagia,Holly Cross, Taxiarchis, Pano Panagia, Agios Antonios (Saint Antonio) and Agia Anna (Saint Anna).
