This small museum was built on the ancient site of Sullectum, a port city south of Mahdia that was very prosperous during Antiquity and had trade relations with other Mediterranean ports, notably Italian ports. This is illustrated in the antiquarium’s showcases.

The visit begins with a mosaic panel figuring a poem (translated on a signpost) celebrating the virtues of swimming and the pleasures of life. At the far end of the room following the hall, another mosaic panel figures a clumsily executed lion of an impressive size: 3 meters high !

Most of the objects displayed in the showcases of the four rooms making up this museum come from the adjoining necropolis which, in fact, yielded the specimens of terra cotta graves; others come from the ancient port installations or from the Christian catacombs built underground in the surrounding fields.
