Surajkund, Faridabad, Haryana

Surajkund is an ancient reservoir of the 10th century, 2 kilometres (1.2 mi) away to the south west from a more ancient dam of the 8th century called the Anagpur Dam; both are located in Haryana, India. Surajkund (literal meaning is 'Lake of the Sun') is an artificial Kund (‘Kund’ means “lake” or reservoir) built in the backdrop of the Aravalli hills with an amphitheatre shaped embankment constructed in semicircular form. It is said to have been built by the Tomar king Suraj Pal of Tomar dynasty in the 10th century. Tomar was a sun worshipper and he had therefore built a Sun temple on its western bank.

Another 'kund' by the same name as ‘Suraj Kund’ existed in Sunam city, famous for surajkand mela, tahsil and sub division of the Sangrur District in Punjab. This was sacked by Mahmood Ghaznvi or Taimur Lane. The temple is now in ruins.

The reservoir has been built in the shape of the rising sun with an eastward arc. It is enclosed within a steep embankment made in semi-circular shape made of stepped stones. Rain fall was intercepted here to create a reservoir of 130 m (427 ft) diameter to meet the water shortage in Delhi. It has an area of 40 ha (99 acres). The reservoir provides a grand spectacle, and in the past it was the hunting forest resort. It abounds in dancing peacocks. The reservoir is filled up during every monsoon season but remains dry during summer, before the onset of the monsoon rains. The tank underwent major repairs in the 1920s during the British times.
