It was the first century AD, between 30 and 60, when a rich and cultured character of imperial Rome, perhaps a senator, built his large seaside villa in the place that would have taken the name of Rheginna Minor from the stream, which became simply Minori very time later, with the Swabian domination.

That seaside villa, buried by materials from the eruption of Vesuvius in 79 AD and subsequent mud flows, after having been largely brought to light starting from the middle of the last century, it is today the main monument of Minori and its remains can be admired, including the frescoed parts. Next to it, the Antiquarium houses the finds found during the excavation and offers interesting reconstructions of parts of the original rooms.

The archaeological area is in the city center and in fact Rheginna Minor developed above the buried structure, whose rooms, discovered by chance during construction and considered natural cavities, were used for centuries as cellars, warehouses and even stables in the new town.
