It stands on a rocky outcrop overlooking one of the deepest canyons in Europe and, thanks to its light limestone blocks, it stands out in the heart of a dense forest. The nuraghe Mereu stands at a height of 835 metres on the Supramonte of Orgosolo. The inhabitants of this Barbagia village call it nuraghe intro ‘e padente, or ‘the nuraghe inside the wood’. The Mereu is, in fact, difficult to see if observed from below and from a distance, as it is surrounded by the forest of Montes. However, once you reach it, you will be able to admire a breathtaking landscape, especially the walls of the spectacular gorge of Gorropu to the north-east. Then, to the south, you can see the outlines of the Supramonte of Orgosolo and that of Urzulei.
The nuraghe, built entirely from limestone blocks found on site, has a complex structure, with a trilobate layout, a keep and two secondary towers connected by a curtain wall. Still standing are the main tower with a tholos roof, still intact and about five metres high, and the bastion on the west side.
