With an extension of 32.03 km2, the municipal district of Altorricón lies on the southern part of La Llitera, limiting with El Segrià (Almacelles).

It's not clear what 'small tower' the name could refer to, but hypothesis point to Castle of Vallbona (Catalan Castell de Vallbona) situated north west from the town, or maybe some building that no longer exists in the center of the village.

The secondary water channel of La Mola, derived from the Canal d'Aragó i Catalunya crosses the municipal district diagonally from NW to SE, and is used to irrigate the land all across the territory.

Multiple minor channels distribute the water, namely the ravine of San Bartomeu or the one of Clamorelles.

The locals call the portion of the road that heads south to the N240, la carretera del Butano (Catalan carretera del butà) in honor of the butane gas processing station that once existed at the intersection with the N240.
