Ancient Roman Firefighter Barracks with Marine Mosaic Unearthed Near Colosseum

cultural-heritage · 2026-08-06

The excavation of an eight-room structure adorned with mosaics and frescoes has been announced by Italy's Ministry of Culture, located on Rome's Caelian Hill, close to the Colosseum. While initially believed to be a residence for the elite, it might actually have served as barracks for the vigiles, the firefighters of ancient Rome. Constructed in the second century C.E. and later renovated in the third, the site boasts a marine-themed mosaic reminiscent of one at the Caserma dei Vigili in Ostia. Augustus established a fire brigade in 21 B.C.E., which became a professional unit following a fire in 6 C.E. If validated as a vigiles barracks, this finding could shed light on the origins of early professional firefighting, as noted by Simona Morretta and Daniela Porro.
