Srđ is a low mountain just behind the walled city of Dubrovnik in Dalmatia, Croatia. The mountain, part of the Dinaric Alps, has a height of 412 metres (1,352 ft). At its top is a large white stone cross and Fort Imperial, a defensive structure built by the French in 1810 during the Napoleonic Wars. Srđ is popular with tourists as a viewpoint from which it is possible to see the walled city of Dubrovnik, Lokrum island, the Adriatic Sea and various local attractions.
