The name has Roman origins and comes from the position along the road between Caralis and Turris Libisonis (Porto Torres): it was the sixth milestone, found in the town with the inscription ad sextum lapidem. Sestu is a large municipality with over twenty thousand inhabitants, ten kilometres from Cagliari, occupying the southernmost part of the fertile Campidano plain. It is largely based on agriculture (vegetables, cereals and grapevines) and it is in constant urban and demographic expansion. In the ancient artisan workshops, the ability to create wooden, wrought iron and copper objects, as well as woven baskets, is handed down. If you want to discover the life of times gone by, visit Casa Ofelia, a typical Campidano dwelling.
