In 1664, Croat-Hungarian nobleman Nicholas Zrínyi arrived in Pécs, with his army. Since the city was well into the Ottoman territories, they knew that even if they occupy it, they could not keep it for long, so they planned only to pillage it. They ravaged and burned the city but could not occupy the castle. Mediaeval Pécs was destroyed forever, except the wall encircling the historical city, a single bastion (Barbakán), the network of tunnels and catacombs beneath the city, parts of which are closed down, other parts are in possession of the famous Litke champagne factory, and can be visited today. Several Turkish artifacts also survived, namely three mosques, two minarets, remnants of a bath over the ancient Christian tombs near the cathedral, and several houses, one even with a stone cannonball embedded in the wall.
