It stands on the hills and is delimited to the south by the basalt platform of Assolo, to the east by the river Imbessu, to the north by mount Grighine and to the west by Brabaxiana of Usellus. Villa Sant'Antonio is a village with just 350 inhabitants in the Alta Marmilla region, which occupies an area rich in natural attractions and rare archaeological evidence, like menhirs. The little village emerged in the early 18th century as a novenario (small rural village) around the church of Sant'Antonio abate, built to consecrate the place in which the simulacrum of the saint was discovered. It didn’t take on its current name only 1985. Agricultural and breeding activities are its main economic resources. The hilly territory, rich in springs, is covered by thick Mediterranean scrub and lush holm oaks and cork oaks. Along the Imbessu valley, there are green alders, willows and tamarisks.
