Aglientu is located 420 meters above sea level and covers an area of 148.56 square kilometers with a population of 1,207. The birth of the town is closely linked to the town’s church dedicated to St. Francis of Assisi, built at the behest of Charles Emmanuel III and Victor Amadeus III and erected between 1774 and 1776. From 1777, the church became a meeting place in which to celebrate normal sacramental activities with the first officiating priest (pro-parish priest) Don Antonio Cossu, and near it appeared the so-called kitchens, places of a socio-economic and fair character. Only around 1850 did some wealthy families begin to build houses in which to stay periodically, and in 1859 the country church became a parish surrounded by a small village. The number of buildings increased only gradually in the first half of the 1900s, as the autarkic economy of stazzi continued to take hold. Aglientu became an autonomous municipality from Tempio in 1959. In addition to its characteristic town center, Aglientu boasts a coastline of about 30 kilometers along which the granite heights of Monti Russu, stretching toward the Gulf of Asinara, alternate with beaches that frame a sea of rare beauty.
