Qasr Al Saneh is an appropriate place to start a tour of Madain Saleh, as it reveals many of the essential elements of Nabataean funerary architecture: a relatively unadorned facade; the two five-step motifs at the top; a simple interior burial chamber with shelves for corpses; and inscriptions above the doorway. Built around AD 50, Qasr Al Saneh was in use for just 50 years before the Nabataean kings were overwhelmed by the Romans.
