The siq, which was the main road leading into the ancient city, began at the dam and ended at the Treasury. The three quarters of a mile long narrow gorge that makes up the siq is surrounded by high cliffs that are about 260 feet tall. The colors and textures of the rock walls changed constantly along the way and many of the walls are decorated with carved out niches that were believed to contain religious artifacts. Another wall revealed the badly eroded remains of a life sized relief of a camel caravan.
The ingenuity of the ancient tribe that built the city was very evident as we traveled through the siq and saw the amazing canals carved out of the mountain that were designed to transport water into the city. The Nabataean people also used stone blocks to build dams that not only prevented flooding, but also helped store water for later use.
