Final answer:
The famous Roman baths were a series of temperature-regulated pools that formed an integral part of Roman culture and hygiene, enabled by Roman aqueducts such as the Baths of Caracalla.
Step-by-step explanation:
The famous Roman baths were a series of pools that went from hot water to cold, which were standard features in Roman cities and a vital part of Roman social life. The Romans, renowned for their engineering prowess, facilitated the construction of these bathhouses through the development of an extensive network of aqueducts, which transported water from distant sources directly to the heart of their cities. One of the most iconic examples of such grand bathing complexes is the Baths of Caracalla, which not only contained the typical frigidarium, tepidarium, and caldarium but also included amenities such as gyms, gardens, and libraries.
