This Skull Tower in Serbia was raised by Ottoman troops under general Hurshi Pasha following the crushing of a revolt in 1809, where the rebel leader Stevan Sinđelić in the face of certain defeat as enemies flooded the rebels' position, ignited his gunpowder store and blew his own forces apart rather than face impalement as a punishment for rebellion. The heads of the rebels were then collected by the victorious troops, skinned, stuffed and sent to the capital, and then sent back to Niš. All in all 952 skulls were built into the facade of a mortared tower as a monumental warning to the locals to toe the line and not challenge their distant ruler. Today only 58 skulls remain in the 4,5 m high tower, the gaping sockets remaining in their neat horizontal rows. Note the horizontal wooden beams, reminiscent of the strengthening horizontal brick or stone bands which occur at regular intervals in Medieval castle walls, inclduing in Constantinople's iconic Theodosian city walls.
