Surajkund

In the forested area where the Surajkund and the Anagpur Dam are located, ancient Stone Age relics have been found which are microliths (stone tools) belonging to lower paleolithic era. These were found at 43 sites from Ankhir (a village 17 km east of Mangar Bani) in south to north along Anangpur-Angnpur Dam-Surajkund-Tughlaqabad axis. These sites are on the 'Tughlaqabad-Surajkund Road' and south of 'Surajkund-Faridabad Road', on Anangpur hills, and on Ankhir hill, and on the road embracing the low ridge from Faridabad (Ankhir) to Surajkund.[7] From a study of the prehistoric findings along the ridges of Surajkund reservoir, Anagpur Dam, and around Delhi and adjoining parts of Haryana, it has been inferred that the southern hilly area of Delhi and Haryana was environmentally suited for pre-historic man to settle here.[15]

Paleolithic tools, rock paintings and rock art found in 2021 at various sites scattered inside the Mangar Bani might be extension of Anangpur-Surajkund paleolithic sites.[8]

Anangpal I, first king of Tomara dynasty (c.736- 1052 CE), declared himself an independent ruler and established the Tomar Rajputs of Delhi in the early 8th century.[16] He built his capital in this village and expanded his kingdom from there. He is said to have built numerous palaces and temples during his reign, the majority of which are diminished now.

Last king of this dynasty was Anangpal Tomar (Anangpal II), who had built Delhi's Lal Kot, which was later renovated by Chauhan ruler and also came to be known as the Qila Rai Pithora. Tomara dynasty were overthrown by another Rajput dynasty, the Chahamanas of Shakambhari. The last Chahamana or Chauhan king was Prithviraj Chauhan (the second last Hindu king of Delhi), Qila Rai Pithora (earlier called Lal Kot) was renamed after him.[3][5][17]

The capital of Tomars changed a few times during the course of 457 years they ruled in the northern India. The first capital of the Tomar empire was Anangpur while the last one was Dhillikapuri (Delhi, Lal Kot).[18]

Though historians have not specifically alluded to this tank, it is also said that it was built in 686 AD by Suraj Pal (after whom the tank is probably named) son of Anang Pal I. It is in the form of a segment (semi circular) with the chord on its west side.[13] Another theory for the name 'Suraj' suffixed to the kund (lake) is that it was named after the Sun Temple that existed on the east side of the lake.[4] Archaeological excavations have revealed existence of a Sun temple here based on ruins that can be seen even now. Certain carved stones were recently recovered from the reservoir. Some stones have also been re–used in subsequent restoration works. Historians also claim it was named after King Surajpal himself who built it.[3][5][17] It is also said that Suraj Pal built this lake for his daughter.[19]

The Tomara's rule was followed by that of the Chahamanas and the mlechchha Sahavadina (Shihab ad-Din).[20]

During the Tughlaq Dynasty rule of Feroz Shah Tughlaq (1351–88), the reservoir was refurbished by rebuilding the steps and terraces with stones in lime mortar. On the western bank of the reservoir, a garhi (cave like structure) was built close to the ancient site of the Sun temple.[2]

Even though the Tomar dynasty vanished in the 12th century, the Surajkund has not been affected. It attracted the attention of the Haryana Government to develop the area as a tourist spot by introducing an annual crafts 'Mela' or "fair" titled "Surajkund Crafts Mela" in the precincts of the lake, which over the years has attracted wide publicity and become an iconic event.[21]

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.[3] 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.[17][19][21]

Anagpur Dam, constructed in 8th century, is 2 kilometres (1.2 mi) upstream of Surajkund in the north west. A seasonal stream flows from Anagpur Dam to Surajkund.[13][14]

Peacock lake, downstream and southwest of Surajkund, is delightfully beautiful.[22]

Supreme Court of India, put an end to the illegal mining in the area around Surajkund which was causing ecological disaster and rapid depletion of ground water in the Aravalli hill range between Tughlaqabad and Gurugram via Surajkund. Supreme Court has asked the Haryana Government "to stop all mining activities and pumping of groundwater within a (5 kilometres (3 mi)), radius of the Delhi-Haryana border in the Haryana Ridge and in the Aravali hills."[30]

The storage in the upstream Anangpur Dam, downstream Surajkund and Peacock lake has been seriously affected The catchment area which contributes water flows into the Surajkund (lake) from villages, such as Anangpur, Lakkarpur, Ankhir and Meola Maharajpur, has been used for extensive mining and for large habitations. This has disturbed the drainage system and thus obstructed the gravity flow of rain water from the basin into the reservoir. This has also affected the flora and fauna of the area.[31] The Surajkund lake's drainage basin is part of the Aravalli hill ranges. It is fed from the north western side by a local nullah (stream) that initially feeds the Anagpur dam on the upstream, this dam was built by Samrat Anangpal Tomar.[13][14]

Surajkund falls inside the leopard habitat of Delhi and Haryana which often get killed due to being hit by the vehicles on the Gurugram-Faridabad Road as there is no wildlife crossing underpass or overpass.[11]

Asola Bhatti Wildlife Sanctuary is close to the Surajkund. Mine pits in this area have been converted to wetland habitat, which will improve the ground water regime in the area.[32]

As of 31 July 2021, Head of HAD, Ashok Khemka, informed that the whole area will be extensively surveyed to find any additional sites, entire area of Delhi South Ridge of Aravali in Haryana between Gurugram and Faridabad will be mapped and each site will be GPS tagged. Large scale scientific excavations, scientific dating of paintings and excavated sediments will be undertaken. A proposal to notify this entire area as protected archaeological site has been sent by Haryana Archaeological Dept (HAD) to Govt of Haryana (GoH), and HAD is awaiting gazette notification by the GoH.[8]
