The Baths of Caracalla were built during the time of Ancient Rome between 212-217 CE. Caracalla’s Father, Septimius Severus, started the baths in 206 and then the baths were completed in 217 CE under the reign of Caracalla. Caracalla was one of 3rd century’s most brutal emperors. It was mainly built out of concrete and brick. The outer surfaces were faced with travertine and the inner walls with stucco, and marble, but today most of it has disappeared. The inside was also decorated with mosaics, frescos, and statues. The main buildings of the Baths of Caracalla are arranged around a central hall with a plaster for sports and exercise on each side. Originally, the Baths of the Caracalla were 228 meters long, 116 meters wide, and 38.5 meters tall, occupying thirty acres and fitting 1,600 bathers at once. The design of the baths included high vaulted rooms, groin vaults, dome octagons, semi-circular chambers, and column porticoes. Beneath the rooms of the baths there is a network of service and storage rooms, tunnels, and corridors that made the functions of the baths. Also that was where the heating plant and its furnaces and water supply systems were located. Because the Baths of Caracalla were located at the edge of the ancient city and therefore wasn’t as destroyed as much as the other baths and is the most preserved. Unfortunately during the time of the Renaissance in the 16th century some of the decorations have were taken because of the desire for antiquities and need for building materials. The Baths of Caracalla held opera performances beginning in 1937 during the rule of Mussolini and stopped in 1993. Today, the Baths of Caracalla are a tourist attraction.
