It stands on the plateau of Gollei, in the territory of Dorgali, about ten kilometres from the town, surrounded by rugged hills, millennial olive trees and Mediterranean vegetation. Serra Orrios is one of the best preserved nuragic complexes: here, you can journey through time to a village-sanctuary, built entirely of basalt blocks, representing a purposefully designed proto-urban settlement in terms of size and architectural structure.

You can take a careful look at the well-preserved civil and cultural buildings of the nuragic age. The village consists of a hundred circular huts, built with a base of rows of stones and originally covered with branches. They are simple, or divided into different rooms - also to keep the animals, typical of a society dedicated to agriculture and breeding - overlooking a single courtyard with a well. Niches or closets have been created in the walls. The floors are in stone slabs, cobblestones or simple beaten earth. At the centre was a circular hearth, bordered by stones. Clay, and perhaps cork, was used to waterproof the buildings. The houses are grouped into three blocks, connected by small streets and squares. 'Hut 49' stands out, isolated, and may have been the 'meeting hut', characterized by a curvilinear layout and equipped with a bench-seat and an entrance vestibule.
