The cemeteries, located in a large area surrounding the city outside the walls, were used for a long time, from the Orientalising Age to the Roman time.

During the Etruscan period, Roselle had three types of graves: chamber‑grave, well‑grave, trench‑gave.

Along the west side of the walls it is possible to see chamber graves cut into the bedrock, which seem to date from the Hellenistic age; while the so‑called tombs "alla cappuccina" are of the Imperial Roman period.

The entrance is allowed only to some of the mentioned tombs. It is possible to visit the graves of the Serpaio necropolis, which is along the way for the ancient city, outside the walls. On this road,

which traces an ancient route, among others there are remains of a tumulus grave surrounded by a stone boundary, in the centre of which is a rectangular trench which includes the outside structures of a small burial room. Also remains of small chamber graves of the type diffused in Roselle, face this road: srnall underground tombs provided with a small square room, approached by a dromos, and covered with projecting slabs. The type dates to the end of 7th‑ beginning of the 6th century B.C., but these tombs must have remained in use until the Hellenistic age. By comparing with similar graves of other sites, they appear to be very modest buildings.
