Cippus

cippi) was a low, round, or rectangular pedestal set up by the Ancient Romans for purposes such as a milestone or a boundary post.

In Rome they marked the limits of the pomerium after the city's walls were expanded further out, the course of aqueducts, and the cursus publicus.

Cippi lined up in rows were also often numbered, often featuring the name of the person placing them or the distance to the nearest other cippus.

[1] Between 800–100 BC, cippi were used by the Etruscans as tombstones, which were shaped differently depending on the place and time of origin.

They are found in North Africa, but also in Sardinia (Cagliari, Teti, Tharros), Sicily (Motya) and Spain (Huelva and Barcelona).
