جبل البركل
Foundation tablets bearing Atlanersa's name show that he started a temple dedicated to the syncretic god Osiris-Dedwen at Jebel Barkal, now known as B700. The choice for this location followed from its closeness to the "Pure Mountain"—the ancient name of Jebel Barkal—and the presence of a small New Kingdom chapel there. It is unclear whether Atlanersa ordered the destruction of this chapel to make place for B700, or whether the chapel was already ruined by this time.
