Serrenti is a town of nearly 5,000 inhabitants situated on a gentle slope along the western edge of the south-central Campidano plain, bordered by Riu Cardaxiu. This is the area where the fertile Campidano plain gives way to rolling hills: the landscape begins to change and Mediterranean shrubs take the place of cereal fields. The area is rich in sites of natural, artistic and archaeological interest. The most important of these are the Nuragic sites of Nuraxi Oliri and Bruncu su Nuraxi and the well temple of Cuccui. Prehistoric discoveries of great interest have been found at Sa Tellura. Two large outcrops near the SS131, known as Perda Longa are unique. They are topped by the striking park of Monti Mannu.
The town derives its income mainly from agriculture, growing durum wheat, tomatoes, artichokes, and asparagus. Agriculture is supplemented by various trades, especially stone carving. Near Serrenti there are excellent quality trachyte mines, used in the construction of important sites, such as the capital’s courthouse.
The center of Serrenti is occupied by the 17th-century Parish of Mary Immaculate. The town has two other churches dedicated to St. James, with a festival in late July, and St. Vitalia, who was martyred in the Amphitheater of Cagliari during the rule of Emperor Hadrian. The historic center is characterized by large portals made of Serrenti stone, on the keystone is the symbol of the homeowner’s trade. The municipal administration built a large raw earth building that currently houses the Earth Arts Laboratory run by the City of Raw Earth Association and in which courses are held by the University of Cagliari on raw earth architecture. Each year the laboratory hosts a major international workshop on the earth material and different building techniques.
