The Old Town of Visoki – was declared a national monument by the Decision of the Commission to Preserve National Monuments. The Old Town of Visoki was a medieval royal castle town built during the 14th century on the top of Visočica 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. The primary function of the old town of Visoki was defense, but it was also a place where a lot of medieval Bosnian rulers wrote various documents and charters. The Old Town of Visoki is at the top of Visočica hill, 213 metres (699 ft) high. Its position provides an excellent view at the plains below bordered by mountains Romanija, Jahorina, Treskavica and Bjelasnica in the east and southeast, Bitovnja in the south, the mountain Zec and Vranica in the Southeast, Vlasic in the west, and Tajan and Zvijezda in the north. The entry to the castle is on the southwest side, with two lookout towers.
