Fodor's Expert Review Su Nuraxi

The most extensive of the island's 7,000 discovered nuraghi, Su Nuraxi is on the UNESCO World Heritage list. Concentric rings of thick stone walls conceal dark chambers and narrow passages in a central beehive-shape tower. In the ruins of the surrounding village there are benches, ovens, wells, and other Bronze Age remnants. Tours start every 30 minutes and last about 50 minutes. The same ticket includes entry to a museum and exhibition center in Barumini. If you're driving from SS131, don't be misled to other, lesser nuraghi—follow the signs all the way to Barumini.
