Great conservation
These are some of the ancient largest and best-preserved ancient baths still standing today. While at first glance, you might only see bare brick walls, collapsed porticoes, and beautiful floor mosaics, the entire base structure of the baths remains intact; some parts measure over 30 meters tall and let you really imagine how it must have been in its day. The baths were opened in 216 during the reign of Marcus Aurelius (whose birth name was Caracalla) and remained in use for over 300 years. They were finally abandoned in 537 when the aqueducts feeding the city were destroyed by Barbarian invaders. It had a capacity for about 2,000 people.
