The centre of the town of Zamosc seemed like a minature of the Stare Miasto in Warsaw. But the features of this WHS that made it different were the extensive city walls and fortifications, and the Rotunda.

Built as part of the town's defences, thye Rotunda bacame infamous during WWII as a transit camp and execution site. The communists continued that tradition during their years of oppression. Now it is at the centre of a cemetery, as a memorial to the victims. Each of the cells contains relics of a different atrocity.
