From the Treasury, the passage broadens into what is commonly referred to as the Outer Siq. Riddling the walls of the Outer Siq are more than 40 tombs and houses built by the Nabataeans in a ‘crow step’ style reminiscent of Assyrian architecture. Colloquially known as the Street of Facades, they are easily accessible, unlike many tombs in Petra.
A couple of tombs are worth exploring here. The first tomb (number 67) is unusual in that it has a funeral chamber in the upper storey. The low entryway highlights how the valley floor has risen over the centuries thanks to the debris washed down during flash floods. Nearby, tomb 70 is unusual in that it is freestanding, with a ziggurat-style top that makes it look like a miniature fort.
