Sardinia is a large Italian island in the Mediterranean Sea. It has nearly 2,000km of coastline, sandy beaches and a mountainous interior crossed with hiking trails. Its rugged landscape is dotted with thousands of nuraghi – mysterious Bronze Age stone ruins shaped like beehives. One of the largest and oldest nuraghi is Su Nuraxi in Barumini, dating to 1500 B.C. ― Google
