The Argentiera - Nurra - Gallura area is located in northern Sardinia and consists of two distinct areas, one located towards the northwestern coast (Argentiera - Nurra), the other towards the northeastern coast (Gallura).
The Argentiera-Nurra area is located in the northwestern part of Sardinia and covers an area of 61 square kilometers, equivalent to less than 2% of the total extension of the Geomining Park of Sardinia. From a mining point of view, the area, thanks to the notable metal deposits of lead, zinc, Argentiera silver, exploited since the time of Roman colonization and Canaglia iron, became the most important metal district of northern Sardinia in the 20th century.
The Geomining Park area is divided into several areas, each rich in landscape and environmental aspects:
- the northern area, with a stretch of coast that reveals rather steep and often overhanging cliffs, such as Capo dell'Argentiera (220 m), is particularly important as an area of geo-mining interest, with suggestive mining buildings located in the inlet of the Port of Argentiera, representing a typical example of industrial archeology, near which the Porto Palmas cove extends and where the Anchusa crispa grows, a typical Sardinian-Corsican endemic plant that has recently disappeared from a large number of areas of the island.
- the central area, with the sweeping gulf of Porto Ferro, distinguished by a shoreline of characteristic reddish sand framed by a thick pine forest and the picturesque lake Baratz
- the southern area, characterized by the limestone headland of Capo Caccia (169 m), in the stretch leading to Punta Cristallo in the north, has a series of striking cliffs dominated inland by Mountain Timidone. Another characteristic feature of this stretch of limestone coastline are the numerous karst phenomena: these are mainly caves that contribute to the uniqueness of this area of coastline. Some examples are the Grotta Verde, Grotta dei Richiami and the Grotta di Nettuno, the last one visited by hundreds of thousands of tourists every year.
The Gallura area occupies the northeast part of the island and extends from the Golf of Olbia to Capo Testa.
The economic situation in Gallura is tied to its fortunate landscape and geo-morphological setting.
In fact, the two driving forces of the Gallura economy are tourism along the coasts, and industrial activities related to the processing of cork and extraction of granite in the hinterland.
The landscape, characterized by rugged coastlines etched by deep inlets, safe shelters from the prevailing mistral winds, and beautiful and spectacular sandy bays, fully justifies the significant amount of investments that have flowed into the northeast of the island over the last thirty years.
National and international entrepreneurial interests have been carried out in the tourist localities that, from Olbia to Santa Teresa di Gallura, extend to the areas of Porto Rotondo, Costa Smeralda, Porto Raphael. The second reality is typical in the cork center of Tempio-Calangianus, while, as regards the extraction of granite, it is concentrated in the two extraction hubs of Arzachena-Bassacutena and Tempio Pausania-Calangianus, which provide blocks of raw granite or semi-finished products to local and national sawmills, and whose finished product is marketed all over the world.
