Inside there is a model of nuraghe and a unicum of the Nuragic civilization, or the cylindrical seat-throne in sandstone.The Necropolis of Anghelu Ruju is one of the most important archaeological sites in Sardinia since it has one of the largest and oldest complex of artificial caves, used by different cultures from 4200 to 1800 BC. about. Discovered casually in 1903 and explored in subsequent excavation campaigns until 1967, the necropolis includes 38 domus de janas located near a stream, the Rio Filibertu.

" in the cockpit (older) with irregular floor plans;
" corridors (more recent) normally arranged in T or in a radial pattern.
