What name did Roman citizens give to the vast public bath complex built by Diocletian in Rome?

Roman citizens called the vast public bath complex built by Diocletian in Rome the Baths of Diocletian.

The baths were constructed between approximately 298 and 306 CE on the northeastern side of Rome. They were the largest imperial baths in the city and could accommodate thousands of bathers. The complex contained bathing halls, exercise spaces, gardens, libraries, and other public facilities.

Diocletian dedicated the baths to the memory of the soldiers and civilians who had suffered during the construction of his major building projects. Their scale reflected the resources available to the late Roman imperial government and the importance of bathing in Roman urban life.

Much of the structure was later reused. Michelangelo adapted the central frigidarium into the Basilica of Santa Maria degli Angeli e dei Martiri in the sixteenth century. The surviving halls and National Roman Museum displays preserve the complex’s monumental character.
