The Roman Camp Potaissa is located on a plateau, known as the Citadel Hill, in what is now the city of Turda. It was founded in 168 by the Fifth Macedonian Legion. Over time, it was transformed into a city and then a Roman colony.
Potaissa is rectangular, 573 meters long and 408 meters wide. The camp was surrounded by 2 m thick stone and mortar walls. In front of the walls there was an additional 12 m wide and 2 m deep water ditch. The ruins of the camp survived until the late Middle Ages. Many of the buildings in the center of Turda were built of materials from the camp site.
During the excavation works, numerous architectural elements, sculptures, mosaics, coins and other small items were discovered. They can be seen in the History Museum in Turda, as well as in museums in Budapest and Vienna.
