Tvrtko I of Bosnia
The Old Town of Visoki (";" ";" ) was a medieval royal castle town built during the 14th century on the top of the hill overlooking town of Visoko, Bosnia and Herzegovina. The first mention of the town was on 1 September 1355, in the charter "in castro nosto Visoka vocatum" written by Tvrtko I of Bosnia while he was a young ban. The town was abandoned before 1503, because it is not mentioned in the Turkish-Hungarian treaty from the mentioned year. In 1626, Đorđić mentioned Visoki among abandoned towns.
