Its area, with its 11,003 hectares, is the largest in the province and includes a small part decentralized from the rest of the territory, south of the hamlet of Tornareccio.

The village of Atessa winds on top of a relief from the crescent-shaped plant, isolated on the surrounding countryside, whose highest point is 473 meters, at the Villa Comunale.

The subsoil consists of one of the last ridges where there are ancient stratified sandy deposits, visible in the numerous outcrops of the escarpments, with an ocher-yellow color.

The large hills are thus constituted, on which are found the majority of the districts, connected by a dense network of secondary roads to the most important ones of the valley bottom.

In the Middle Ages it was a fief of various lords including: the Courtenay or Cortinaccio, Philip I of Flanders, the Maramonte, the Counts of Monteodorisio, king Ferdinand I of Naples and the Colonna.
