What Roman public baths in Rome were built under Emperor Caracalla in the early 3rd century?

The Roman public baths built in Rome under Emperor Caracalla were the Baths of Caracalla.

Construction probably began around AD 211 or 212 during the reign of Caracalla’s father, Septimius Severus, and the complex was inaugurated in AD 216. Work and decoration continued under later emperors, so the baths were not completed in every detail at the moment of inauguration.

The Baths of Caracalla were more than bathing rooms. Their vast complex included hot, warm and cold rooms, swimming pools, exercise spaces, libraries, gardens, fountains and richly decorated halls. A hypocaust system heated floors and water, while a dedicated branch aqueduct supplied the baths.

They remained in use until the 6th century, when the Gothic War disrupted Rome’s water supply. Do not confuse them with the Baths of Diocletian, which were larger and built later, or the Baths of Trajan, an earlier imperial bathing complex.
