Domus Romana is a preserved ruin of an aristocratic house from Roman times, which is estimated to be built in the 1st century BC. Remains of the building were discovered in 1881. During excavations, well-preserved mosaics, many statuettes and smaller objects of everyday use were found. A year later the place was made available for sightseeing. Currently, it houses a museum gathering excavations from the Roman period.
The mosaics in Domus Romana are compared to those found in Pompeii and Sicily. During the research work, a large collection of statuettes of the Roman imperial family, coins, glassware, ceramics, toiletries and jewelry was collected. At the same time, over 200 Muslim burials were discovered that date back to the 11th century, when Malta was part of the Fatimid caliphate.
In 1922, the museum facilities were expanded, during which today's neoclassical facade and a large exhibition hall were created. The museum is currently managed by Heritage Malta.
