So do you have any Medieval Castles or walls in your city or generally the area that you live in? Those of you that are from France,England and Germany must have some Castle or Keep or at least some remnants of old walls. My city Thessaloniki,since it was the second largest and greatest city of the Byzantine Empire has Byzantine walls and a small "keep" let's say called Eptapyrgion(Yedikule in Turkish)which means "Seven Towers" and generally the byzantine walls and the ramparts go on for many kilometres in the city. We also have the White Tower which is the symbol of our city,a tall round tower that was built by the Venetians in 1430.Ironically the city was captured by the Ottoman Turks in the same year. On the way to the city where I study there is the Castle of Platamon(Platamon is a small town)which was built and owned by Godfrey Villardouin the writer of the chronicle of the Fourth Crusade,near 1204 when the Crusaders captured Constantinople and established a feudal empire in Greece.
