Rome - The world's largest ancient thermal bath, Caracalla.

TERME di CARACALLA is one of the largest ancient thermal bath complexes in the world, located in the ancient Roman public baths in the city of Rome, built between 212 and 216 AD during the Roman Empire. Today, its ruins have become a tourist destination. The bath complex covers an area of 13 hectares, with the main building measuring 228 meters long, 116 meters wide, and 38.5 meters high, capable of accommodating 2,000 people bathing at the same time. The bath complex is not only a set of baths, but also a place for entertainment and leisure, with a public library storing books in both Greek and Latin. There is also a shopping center outside the bath complex. The entire building is heated by hypocaust, a system that heats water by burning coal or wood underground. In the early 20th century, the design of the bath complex still inspired some modern buildings, including the Pennsylvania Station in New York and the National Assembly Building in Bangladesh. Although the bath complex is now in ruins, the exquisite mosaics on the floor and walls, as well as the marble columns, demonstrate the prosperity and superb craftsmanship of ancient Rome. The bath complex is not just a place for bathing, but also the core social and entertainment venue. It is definitely a must-see to learn about ancient Rome. The ticket price is 14 euros. Address: Via delle Terme di Caracalla, 00153, ROMA.
