The Hercules Villa is situated the northeastern and northern edge of the former Military Town and belongs to the row of decorated palaces, baths, sanctuaries and habitations that stood along the riverbank across from the Governor's Palace. The Hercules Villa located in Meggyfa Street.

The central core of this building must have been built during the first half of the AD 2nd century. At the beginning of the third century this building was expanded, equiped with floor-heating and decorated with mosaic floors. In the three adjacent habitation rooms, most of these mosaic floors collapsed into the channels of the hypocaust heating system. Only details of the Pannonian made geometric framing motif survived in the two southern rooms, while in the third, the greater half of an emblem was recovered. This section, showing the fight between Hercules and Nessos the Centaur, formed a central field in the floor.

It is likely that this mosaic was made in an Alexandrian workshop. To date, it is the only known imported mosaic not only in Aquincum but anywhere in Pannonia. The floor of the tablinum shows a merry and tipsy Dionysean thiasos. In the surviving section, Amor offers a bunch of grapes to an approaching tigress. Mosaic floors decorated the separate baths as well. It shows a pair of boxers. The walls were decorated with frescoes. Door- and windowframes, stucco niches and sills were ornamented with flowers. Reconstructions of some of the most typical motifs are on exhibit in the tablinum.
