The scale model of the castle of Despot Stefan Lazarevic, the work of the sculptor Kolja Milunovic, is placed approximately in the centre of the medieval castle. This part of the fortress underwent the greatest changes and the greatest destruction over time, especially at the end of the 17th century. During the Turkish siege, a large explosion of gunpowder almost completely destroyed the ramparts and towers of the castle. By clearing these ruins, a mostly flat space was obtained, completely different than it was originally. Thanks to the scale model, it is easy to imagine the previous appearance of this part of the fortress.
