Nafpaktos Epic castle from a drone's view. Nafpaktos Castle is one of the most impresive and well-preserved castles in Greece and one of the most beautiful castles in Europe. It is built on the hill above the city and uniquely combines the strong mountain citadel, the fortification of the city and ends in 2 towers that close the entrance of the small port. The view from Nafpaktos Castle is magnificent as it overlooks the entrance to the Corinthian Gulf and the Charilaos Trikoupis Bridge. Take a look at this epic castle from the Greek Orthodox Vlogger's drone.
