Immersed in the picturesque countryside of Medio Campidano, just a short distance from the historic Terme di Santa Maria de is Aquas, the Santu Domini site treasures a fascinating journey through time. On a small panoramic hill about 93 meters high, the millennial history of Sardinia reveals itself at a single glance: the remains of an ancient nuraghe (historically classified as a single-tower structure but surrounded by imposing basalt defensive walls) dialogue just a few meters away with the evocative ruins of the medieval country church of San Domino.
