The Piri Reis Museum is housed in a stone tower overlooking the harbour walls, the sole remainder of the Byzantine town of Kallipolis, which gave the present town and peninsula their name. The tower is named after the Turkish cartographer Piri Reis, whose statue stands on the coast near the otogar, looking out to sea. The fruit of his life’s work, dating back to 1513, was the first known map to show the Americas in their entirety. Inside there’s a large, shallow well and an upstairs chamber displaying copies of pages from Reis’ famous map, together with a hotchpotch of historical exhibits and remnants from the Gallipoli battles.
