This is Nebojša's Tower (NEH-boy-sha), located just below the Kalemegan Fortress's walls. It dates from around 1460. "Nebojša," which is also a popular boy's name, means 'not afraid of anything.' Legend says when, after a long battle in 1521, the Turks finally seized nearly all of the Belgrade Fortress, the tower rose into the air so that it could never be captured.
