The Street of Facades
It is name given to the row of monumental Nabataean tombs carved in the southern cliff face that lies past the treasury and adjacent to the outer Siq. When you pass the treasury, the Siq begins to widen gradually as it reaches into an open area. On both sides, there are a number of Nabataean burial interface decorated with grindstones along with other decoration; and some of these interface were destroyed by natural factors. It is believed that these interface represents some of the senior officials in the city or princes.
