Bobovac was the Royal seat of the Bosnian rulers from the reign of ban Stjepan II Kotromanich to the end of the Bosnian kingdom. Bobovac represents a typical example of a Medieval architectural and urban ensemble, perfectly integrated into its natural setting. The parts of the complex are the Royal Court with a gate decorated with a gothic portal bearing the coat of arms of King Tvrtko II, the Upper Palace, forecourt, the Main tower, the Lower Palace and the Franciscans’ Palace.
Close to the Palace complex is the Burial Chapel of the Bosnian Kings and the Grand Church. Three royal tombstones were discovered in the chapel - those of Kings Ostoja, Tvrtko II and Tomash. During the reign of King Tomash and his wife Katarina began the construction of the Grand Church, but it never advanced beyond the layout of the foundations.
