The history of the construction of the Tamasin Palace, according to some historians, dates back to the year 782 AD. This historical landmark is one of the desert palaces whose ruins still bear witness to the history and authenticity of the region. It tells the story of the tribes that passed through it and built the “Rig Valley” civilization. Historical accounts differed about the construction of the Tamassin Palace, but historians, including the scholar Ibn Khaldun, believe that the palace was founded by the Berber Riga tribe, after which the Wadi Rig region was named, and it is the story closest to the truth.
