Agrabit Reservoir. A special installation made by Arabs collecting water in the desert. Visited the Agrabit Reservoir to climb the castle overlooking the Reservoir. The reservoir is divided into two pools, small pools are used to collect rainwater, while large pools are used to settle impurities and form clear water. Because Kailuvan is a water-scarce region, the locals built 15 reservoirs in 862 AD, a symbol of the ingenuity of the people living in the desert.
