Твртко I
The Old town of Visoki was a famous medieval royal castle town during the fourteenth century, located in 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 appears to have been abandoned before 1503, as it is not mentioned in the Turkish-Hungarian treaty that was established that year. In the year 1626, Đorđić mentioned Visoki among abandoned towns.
