New concept designs for the Sharaan resort by Jean Nouvel revealed today offer a deeper understanding of the architect's daring vision for AlUla, the cultural oasis in north-west Arabia. Located deep within the Sharaan Nature Reserve, the designs draw on the nearby Nabataean wonders of Hegra, Saudi Arabia's first UNESCO World Heritage Site. In a world-first, this 2,000-year-old architectural legacy is being revived by Jean Nouvel for potentially the first time since the Nabataeans carved into the region's millions-of-years-old sandstone rock.
