A tower built of Human Skulls. Niš

The Ottoman Empire was not renowned for being kind and gentle to its subjects, particularly those from lands it had invaded. Fear was a weapon used to maintain control and punish those that stood up to the caliphate. When the Serbians rose up against the foreign invaders in 1809, the revolt was quickly crushed and a gruesome reminder of the fate that awaited those who rebelled was built in Niš, a tower built of skulls.
