This photograph was taken at Jantar Mantar, one of India’s most famous astronomical observatories, located in Central Delhi. It was built in 1724 by Maharaja Jai Singh II of Jaipur, who then went on to build other observatories in Jaipur, Varanasi, and Mathura. It was used to make astronomical tables and predict movements of the planets and the sun. Its name is derived from yantra meaning instruments and mantar meaning formula.
Due to the construction of several high rise buildings around the monument, it is no longer used for astronomical purposes. It however continues to be one of the biggest tourist attractions of the capital city.
