The Klis fortress is situated on the hill of the same name and in the past, thanks to its strategic importance, was a notable defensive position. Situated on the high, natural sheer rocks above the crossing between the continental and coastal parts, a beautiful view extends over the surrounding parts areas and even as far as the island of Vis. The Fortress has three levels and is surrounded by a triple ring of city walls whilst the most important parts of the fortress are the Kneževa kuća (Prince House), the church of St. Vitus, the powder-magazine, the officers' barracks and the Oprah tower.
