An unusual landscape halfway between Alghero and Stintino: abandoned mines and an (almost) uninhabited village framed by silver cliffs and lapped by the shimmering reflections of the sea. Argentiera retains the primordial and mysterious charm of a place frozen in time. After the end of the mining epic between the 19th and 20th centuries, today it is one of the most significant and evocative European sites of industrial archaeology, an integral part of Sardinia's geo-mineral park and a UNESCO World Heritage Site. Ruins coexist with new buildings, all around sheer rock faces, mountains of mining slag and coves accessible by paths through unspoilt nature. A spectacular setting, the 1968 set for the opening scene of Boom!, starring Betty Taylor and Richard Burton, which is now a hiking destination.
