For more than three thousand years, six stone guardians have been stationed in front of its funeral area, contributing to increasing the mystical atmosphere of the site. The Nuragic settlement of Tamuli extends along a plateau about four kilometres from Macomer, the main town in the Marghine region. The complex dates back to the Middle and Late Bronze Age, between the 16th and 13th century BC. You will immediately notice the three Tombs of Giants positioned side by side. Tomb 1 is the best preserved: it has a large semicircular area, crossed by a seat, with the entrance in the middle, obtained via a hole created on a trapezoidal slab. The body of the tomb is apsidal, with a rectangular floor plan. On the south side of the tomb you will see the most distinctive element of the site, locally known as sas perdas marmuradas: these are six anthropomorphic betyls, conical in shape and arranged in two groups.
