The emblematic walled Vila Vella or Old Town of Tossa is the sole remaining fortified medieval town on the Catalan coast and was listed as an artistic-historic monument in 1931. Built in the early 13th century to protect the town from pirate attacks, the original enclosed area, with its battlements, has remained almost entirely intact.The original perimeter walls and battlements have four large towers and three cylindrical towers. The best-known towers are Joanąs Tower overlooking the bay; Clock Tower at the entrance to the parade ground, thus named because it was the only public clock in the town; and Codolar Tower (or Keep), located next to the former Governor’s House, overlooking Codolar beach.
