Visoko is a city located in Zenica-Doboj Canton of the Federation of Bosnia and Herzegovina. Located between Zenica and Sarajevo, Visoko lies on the Bosna river where the river Fojnica merges into it.
The Visoko region has evidence of long continuous occupation, with the first traces of life dating back to 5th millennium BC, and archaeological excavations of Okolište have found one of the biggest neolithic settlement belonging to Butmir culture in southeast Europe.
It was an early political and commercial center of the Bosnian medieval state, and the site where the first Bosnian king Tvrtko I was crowned. Old town Visoki, located on Visočica hill was politically important fortress, and its inner bailey Podvisoki was an early example of Bosnian medieval urban area.
Visoko is named after the Visoki Castle and the town of Visoki, which occupied Visočica hill. Podvisoki, Mile (today’s Arnautovići), Biskupići and Moštre – together known as Visoko valley – were the early center of the medieval Bosnian kingdom. Many historical charters were made and written in Visoko valley, including the charter of first Bosnian king Tvrtko I Kotromanić in 1355, in castro nostro Vizoka vocatum which was also the first direct mention of the town of Visoki. Visoki was also a place where many important documents and legislation of medieval Bosnia were signed and written. The town of Visoki had a defensive role in protecting trade center Podvisoki (Subvisoki) which was located just below the town and was one of earliest examples of the medieval urban environments in Bosnia. Podvisoki was long time main trade center in medieval Bosnia.
Old Town „Cajengrad“ is a medieval fortress which served to defend Bobovac from enemies and today represents an archaeological site. The fortress was discovered by accident when a few locals found a stone structure with windows during a rock climb. Mile, which is believed to be one of the residences of Bosnian kings, is located 5 km from the city’s centre. Findings so far show that Stjepan II Kotromanic and Tvrtko Kotromanic resided there. This is also the place where Tvrtko was crowned and buried at the Church of St. Nicholas.Mile is also known for the trade agreement between Bosnia and the Republic of Ragusa (Republic of Dubrovnik) signed in 1189 under the Charter of Kulin Ban, the oldest preserved Bosnian document written in bosancica (Cyrillic).
