History and description

Though the Baths do not exist anymore, one can get an idea of its immense lay-out by visiting the Santa Maria degli Angeli e dei Martiri church and by walking around the Piazza della Repubblica. The porticoed half of the Piazza echoes the former semi-circular exedra of the Terme.

There were two rooms on each side of the exedra, one of which has been transformed in the Church of San Bernardo alle Terme.

There was a rectangular calidarium with three semi-circular niches, then the tepidarium and the pool came, all on a central axis with rooms arranged symmetrically on each side of this axis. The rooms that were to be found between the gymnasium and the basilica are now part of the Museo delle Terme.

The famous Octagonal room, now part of the Roman National Museum, can be found at the cross-roads with Via Parigi.

Where nowadays the church stands, the central room of the Terme, the Frigidarium, as well as the basilica and part of the pool were to be found.

The Terme stayed in use for more than 2 centuries, until the year 537, when the Goths sacked Rome, destroyed some of the aqueducts, and the water leading to the Terme was cut off.

The museum’s collection consists of a great many statues, sarcophagi and funerary trousseaus, often found in areas outside Rome. There are many terracottas and there is also a section on the earliest history of the Latin peoples. The epigraphical section dates back to the first half of the 20th century.

Before one enters the actual museum, one walks through the so-called Garden of the Five Hundred, which at its center has an impressive marble fountain. The museum itself is located around a peaceful courtyard, called the Cloister of Michelangelo, where a number of minor statues can be seen.


What is not generally known, is that the Terme di Diocleziano gave their name to the main railway station Roma Termini.
