Not to be outdone, Siddhraj Jaysinh built the reservoir Sahasralinga Talav, meaning "lake of a thousand lingas”, just north of Rani Ki Vav in 1084, over a lake originally known as Durlabh Sarovar, built by the King of Durlabhray. During his rule he had many artificial tanks built in different parts of Gujarat, but this one surpasses all the others, technologically, artistically, and spiritually. Like in Rani Ki Vav, the architecture represents the integration of careful water management with the sanctity of water. Of the 7-hectare spread of ruins only 20 percent has been unearthed, excavated in 1942-43, and though it was destroyed three times in attacks, its splendor is still evident. There is a finely carved three-ringed sluice gate that channeled water from the Saraswati river into the reservoir, and it is said that the lake had inbuilt natural filtration. The reservoir contains elaborate sculptures of deities and impressive columns that once supported a ceiling. On the banks were the remains of a Shiva temple with a colonnade of forty-eight pillars, and numerous small temples, each with a small phallus on a vulva, representing the creative spirit and fertility of Shiva and Parvati.
