The giants' tomb of Barrancu Mannu, locally known as Sa fraigada, is a Nuragic monument located on a hill west of the Baccu Mannu stream, near an ancient village with defensive walls. This "row" tomb has a 20-meter apse-shaped main body with a truncated ogive burial chamber and a semicircular exedra of almost 15 meters. The façade, almost 5 meters high, preserves a cup on the architrave. The construction technique suggests a dating to the Middle Bronze Age (1400-1300 BC), in the absence of excavations.
