Walls of Ston

Walled city Croatia, Croatia

The Walls of Ston are a series of stone defensive walls, originally more than 7 kilometers long, which surrounded and protected the city of Ston, in today's southern Croatia. The wall, now 5.5 kilometers long, connects Ston to Mali Ston and has the shape of an irregular pentagon. It was completed in the 15th century, together with its 40 towers (20 of which have survived) and 5 fortresses. The walls of Ston were known as "the European Wall of China".
