Al Ula Regional Museum and Interpretation Centre are located in a privileged enclave beside the desert in addition to being close to the worldwide famous Nabatean ruins of Madain Saleh. The winding shape of the mountains, canyons and the Arabian fortress are key to explaining this solution. This singular building reflects the environment and its historical and cultural heritage with regard to constructive traditions. This solution is made of mud walls, a vernacular building technique using compacted earth and pigments poured into a vertical formwork in layers. As a result, this method provides this building with a vast expressiveness that evokes the texture of the mountains nearby.
