Jal Mahal (meaning "Water Palace") is a palace in the middle of the Man Sagar Lake in Jaipur city, the capital of Rajasthan, India. The palace was originally constructed in 1699; the building and the lake around it were later renovated and enlarged in the 18th century by Maharaja Jai Singh II of Amber.
The palace is a showcase of Rajput and Mughal styles of architecture.
The building has a picturesque view of Man Sagar Lake, but owing to its seclusion from land is equally the focus of a viewpoint from the Man Sagar Dam on the eastern side of the lake in front of the backdrop of the surrounding Nahargarh.
he palace, built in red sandstone, is a five-storied building, of which four floors remain underwater when the lake is full and the top floor is exposed.
