The Sarrabus-Gerrei territory is located in the eastern part of Sardinia and covers an area of 575 square kilometers, equivalent to 15% of the total area included in the Geomining Park of Sardinia.
It is thus the second largest area among those included in the Park, which is also very representative in terms of variety; diffusion and importance of the mining activities that took place there.
From a mining point of view, the area, due to the abundance of metal deposits such as lead, zinc, copper and above all silver, became the island's second most important mining district in the last century.
The rich mining heritage of the region is set in an environmental and landscape context of particular interest, characterized by a rather varied morphology, with some peaks exceeding 1,000 meters and numerous others over 700 meters.
From a geological point of view, these regions are characterized by lithotypes of the Paleozoic basement, both metamorphic and granitic, while limited Tertiary age coverings are found in the northern areas; Quaternary deposits are instead frequent in the eastern areas, at the junctions between the mountainous hinterland and the coast, as well as along the principle river tracts.
The Sarrabus-Gerrei territory is also a vast natural area of considerable environmental interest thanks to the variety and diffusion of certain plants, where majestic forests and dense expanses of Mediterranean scrub are replaced, in those areas of anthropic degradation, by the reforestation of state forests, out-and-out “green lungs” made up of conifers.
The presence of various types of archaeological features is remarkable.
