Boasting a capacity of over 3000 people, the Baths of Diocletian was constructed by Emperor Diocletian from 298 to 306 AD. Spanning an impressive 120,000 square metres, the complex is made of bricks coated in marble, and is adorned with mesmerizing mosaics and sculptures. This is more than just a bathhouse however, as one can find a gym and a library here too. The public baths are also capable of providing either hot, cold or tepid water.

Since 2008, it became part of the National Museum of Rome, with only one section open to the public. Marvel at the high ceilings of the baths and be impressed by the two tombs embellished with frescoes and stucco, dating back to the 2nd century. Calm your senses by taking a leisurely stroll through an enchanting 16th-century garden featuring almost 400 different works of art, including statues, reliefs, and sarcophagi. These baths sure are steeped in history.
