About the National Roman museum – Baths of Diocletian

Baths of Diocletian side walls

The baths are part of the National Roman Museum – a collection of amazing statues, art and other artefacts spread across 4 museums in Rome (more about them later).

Many of the artefacts from the museum itself have been distributed elsewhere. But don’t worry, there is more than enough to see. Opened to the public from the year 2008, the Baths of Diocletian architecture is hugely impressive.

Check out in particular the exhibition on early Latin peoples, and marvel at how this structure was even build way back then. Beautiful frescoes can be witnessed high up on the ceilings, and don’t forget a long stroll in the gardens to marvel at the artwork on display. Definitely on our list for things to do in Rome once you have hit off the Colosseum and the Vatican City.

Baths of Diocletian Plan

Floor plan Baths of Diocletian

The massive structure, which also included a gym, library and lots of different areas for bathing, spread over 130,000 metres squared. Here, hot, cold and warm baths were available for public use.

From the huge site, located on the Viminal hill, only a small portion is open to the public, but you can really appreciate the scale. Especially if you climb up the Santa Maria degli Angeli for the best views.

The plan for the Baths was modelled on the Baths of Caracalla, with the aim of being bigger and more impressive. The central area was located within a large square, which totalled 376 x 361 meters, and became the focal point for life in the area.

Details about Construction

Built entirely in brick encased in beautiful marble. Over ten thousand Christian slaves undertook this tedious and laborious work.

The construction of the Baths of Diocletian Rome took 8 years, during which many of the slaves died of exhaustion. The Santa Maria degli Angeli Basilica was constructed in memory of those that lost their lives.
