Baths of Caracalla. The Baths of Caracalla in Rome, Italy, were the city's second largest Roman public baths, or thermae, likely built between AD 212 and 216/217, during the reigns of emperors Septimius Severus and Caracalla.
   They were in operation until the 530s and then fell into disuse and ruin. However, they have served as an inspiration for many other notable buildings, including the Baths of Diocletian, Basilica of Maxentius, the original Pennsylvania Station and Chicago Union Station.
   Art works recovered from the ruins include famous sculptures such as the Farnese Bull and the Farnese Hercules. Today the Baths of Caracalla are a tourist attraction.
   Construction of the baths was probably initiated by emperor Septimius Severus and completed during the reign of his son, Caracalla. They were inaugurated in AD 216.
   The baths were located in the southern area of the city, Regio XII, where members of the Severan family commissioned other construction works: the via nova leading to the baths and the Septizodium on nearby Palatine Hill. For work to have been mostly completed in the time of Caracalla, workers would have had to install over 2,000 metric tons of material every day for six years in order to complete it between 211 and 216. Work on additional decorations continued under Caracalla's successors Elagabalus and Severus Alexander. The baths were likely mostly finished by 235. Later renovation
