Ancient Roman baths, known as thermae, were large public bathing complexes that served as social and recreational centers. They typically included various rooms with different temperatures, such as the caldarium (hot bath), tepidarium (warm bath), and frigidarium (cold bath). These baths were often elaborately decorated with mosaics and sculptures, showcasing the importance of hygiene and relaxation in Roman culture. Visitors to the baths could enjoy not only bathing but also exercise, reading, and socializing. The baths were heated using a system called hypocaust, which circulated hot air beneath the floors. This innovative engineering contributed to the popularity and longevity of the Roman bathing tradition.
