The Baths of Diocletian

The Palazzo Montemartini is the closest hotel in Rome to the Baths of Diocletian.  The entrance is just 150 metres from the hotel and can be reached in a matter of minutes on foot by walking along the Via Volturno and Viale Enrico De Nicola.

The Baths of Diocletian are the largest baths dating back to ancient Roman times, construction of which commenced in 298 B.C. and which were inaugurated in 306 B.C.

The centre of the entire site was made up of pools filled with water at different temperatures: the calidarium (hot), the frigidarium (cold) and the tepidarium (warm water).

Next to these are the hall of the central basilica, the outdoor pool and numerous other rooms.

Majestic and rich in archaeological history, the baths covered an area of almost 14 hectares.  Even as late as the 5th century there were still 2400 pools with a central block that measured 250 x 180 metres and was able to accommodate up to 3,000 people at the same time.


Today, part of the perimeter is occupied by the Church of Santa Maria degli Angeli which was built following the transformation of the baths into a Basilica which occurred in 1561 at the behest of Pope Pius IV.

In 1889, the complex became the seat of the National Museum of Roman Antiquities, the guardians of archaeological collections and finds from various excavations.  In the cloister you will be able to see 400 sculptures which are divided between statues, sarcophagi, reliefs and architectural artefacts.

And let’s not forget about the gallery and the sections which are dedicated to the Latinate peoples, the culture of the Lazio region from the late Bronze Age and Iron Age and the Latin language.

The multimedia room enables you to experience a virtual exploration of the monuments and sites along the ancient Via Flaminia thanks to a special system that has been installed in the building.

The Octagonal Hall is home to some of the sculptures that were discovered in the baths.

The Baths of Diocletian provide a venue throughout the year for special events and performances.  They can be visited from Tuesday to Sunday from 09:00 to 19:30.

The Baths are accessible for disabled visitors thanks to the absence of any architectural barriers and the presence of ramps and lifts.  Wheelchairs and suitable toilets are also available.

Educational tours can be organised for individuals, for groups and for schools.

Audio-guides are available and there is a bookshop and cloakroom.
