Rupa Bhawani, a great female saint of Kashmir from the Sahib clan of Kashmiri Pandits, discovered the freshwater spring in the Zabarwan Range. Her family name was Sahib and locals originally called this water source Chashme Sahibi before the name shifted to Chashme Shahi.
Emperor Shah Jahan issued an order in 1632 AD to build a garden around the existing spring. Governor Ali Mardan Khan executed these instructions for his son Prince Dara Shikoh while the structure measures 108 meters long and 38 meters wide.
The site lies within Srinagar city limits northeast of the airport terminal building with Boulevard Road running alongside Dal Lake connecting the garden to Raj Bhawan governor house. The location remains adjacent to the Governor's residence throughout the year.
Local belief holds that the spring water possesses healing qualities for those who drink it which led former Premier Jawaharlal Nehru to arrange shipments of this water to travel all the way to Delhi. He collected samples directly from the source before they were transported northward over hundreds of miles across varied terrain to reach the capital city.
