One of the main sacred stations along the Siq is the free-standing block monument with a large votive niche on the western side, located about halfway through the Siq. It is a facade with two pilasters and an entablature framing two remarkable betyls. While the smaller betyle on the right is plain, the larger one on the left has eyes consisting of two square eyes separated by a rectangular band for the nose, which form a schematic representation of a human face. The holes that hold traces of stucco are drilled in the architrave and the niche.  The niche, which was uncovered in 1977 by the Department of Antiquities, is facing people on their way out of the city, and it is the largest known in the Siq.  The Betyls are thought to represent Dushara and Al Uzza, the two most important Nabataean gods in Petra.  It is possible to date the niche of the Siq to the first half of the 1st century A.D.
