Plan of the Baths of Caracalla, Rome, Italy, 212-6 CE
“The thermae remained in use until the 6th century when the complex was sacked by the Ostrogoths during the Gothic War, destroying the hydraulic installations. In the early 20th century, the design of the baths was used as the inspiration for several modern structures, including Pennsylvania Station inNew York City, USA and National Assembly Building in Dhaka, Bangladesh. At the 1960 Summer Olympics, the venue hosted the gymnastics events. The extensive ruins of the baths have become a popular tourist attraction. The baths are open to the public for an admission fee of 6 Euros, which does not apply to students or pensioners from the EU. Access is limited to certain areas to avoid damage to the mosaic floors, although such damage is already clearly visible. Also, a total of 22 well-preserved columns from the ruins are found in the church of Santa Maria in Trastevere, taken there in the 12th century.”
