Chashme Shahi or Chashma-i-Shahi (the royal spring), also called Chashma Shahi, is one of the Mughal gardens built in 1632 AD around a spring by Ali Mardan Khan, a governor of Mughal emperor Shah Jahan as per the orders of the Emperor, as a gift for his elder son Prince Dara Shikoh. The garden is located in the Zabarwan Range, near Raj Bhawan (Governor‘s house) overlooking Dal Lake in Srinagar, Kashmir.
Chashme Shahi originally derives its name from the spring which was discovered by the great female saint of Kashmir, Rupa Bhawani, who was from the Sahib clan of Kashmiri Pandits. The family name of Rupa Bhawani was ‘Sahib’ and the spring was originally called ‘Chashme Sahibi’. Over the years the name got corrupted and today the place is known as Chashme Shahi (the Royal Spring).
The garden is 108 m long and 38 m wide and is spread over one acre of land. It is the smallest garden among the three Mughal gardens of Srinagar; the Shalimar garden is the largest and the Nishat garden is the second largest. All the three gardens were built at the left bank of the Dal Lake, with Zabarwan mountains at the backdrop.
The topography and the steepness of the land has led the formation of the garden. The main focus of the garden is the spring which flows down in terraces and is divided into three sections: an aqueduct, waterfall, and fountains. A two-storey Kashmiri hut stands at the first terrace which is the origin of the spring. The water then flows down through a water ramp (chadar) into the second terrace. The second terrace serves as a water pool and a large fountain stands at its centre. The water again flows down through a water ramp into the third terrace, which is a square five-fountain pool. It is the lowest pool at the entrance of the garden. The visitors are received through a flight of stairs on both sides of the terraces which leads up to the origin of the spring. The water of the spring is believed to have some medicinal properties.
