Jagmandir Island in Lake Pichola is named after Maharana Jagat Singh (1628-52) who made a number of additions to it. The future Emperor Shah Jahan of the Mughal dynasty, took refuge on the island in 1623. The north part of the island is a courtyard garden enclosed by a summer palace and a cloister-type arcade. It contains a fountain pool and various chhatris. The southern part of the island is more horticultural, with trees, lawns and flowers. The views of Lake Pichola are excellent and diligent garden tourists may be reminded of Isola Bella in Italy.
Jagmandir Island is also used as a garden wedding venue.
