Along the way Casone Grotta, that defines the limits of the municipalities of Boscoreale and Pompeii, since 1986 SAP undertook a systematic survey of excavations that brought to light interesting areas, with walls in opus reticulatum and angular toothing in opus vittatum, relevant to a Roman villa. Studies are mainly focused on identifying the ridges of the walls, the portion of interest consisting in a compartment covered by a gabled roof which has, on the wall opposite the entrance, a perfectly preserved lararium with decoration in stucco (this area of the complex was covered by a canopy). For safety reasons, the monument was reinterred. The villa dates back to the late Republican Age, towards the end of the first century BC.
