The Baths of Caracalla are the ruins of a massive and luxurious ancient Roman public bathhouse located in Rome, Italy. Built in the early 3rd century AD under Emperor Caracalla, they were among the largest and most opulent bath complexes in the Roman Empire, featuring hot and cold baths, libraries, gardens, and sports facilities. Today, the impressive remains offer a glimpse into Roman engineering and daily life, and the site is often used for summer concerts and cultural events.
