Skull Tower is a stone structure embedded with human skulls located in Niš, Serbia. It was constructed by the Ottomans following the Battle of Čegar of May 1809, during the First Serbian Uprising. During the battle, Serbian rebels under the command of Stevan Sinđelić were surrounded by the Ottomans on Čegar Hill, near Niš. Knowing that he and his fighters would be impaled if captured, Sinđelić detonated a powder magazine within the rebel entrenchment, killing himself, his subordinates and the encroaching Ottoman soldiers. The governor of the Rumelia Eyalet, Hurshid Pasha, ordered that a tower be made from the skulls of the fallen rebels. The tower is 4.5 metres (15 ft) high, and originally contained 952 skulls embedded on four sides in 14 rows.
