Jal Mahal (meaning “Water Palace”) is a palace in the middle of the Man Sagar Lake in Jaipur city, which is the capital of the state of Rajasthan, India. The palace and the lake around it were renovated and enlarged in the by Maharaja Jai Singh II of Amber in the 18th century.
The Jal Mahal palace is an architectural showcase of the Rajputana style of architecture (common in Rajasthan) on a grand scale. The building has a scenic view of the lake itself 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 hills.
The palace constructed 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. The chhatris on the four corners are octagonal.
The hills surrounding the lake area, towards the north east of Jaipur, have quartzite rock formations, which is part of Aravalli hills range.
Within the lake area, the ground area is made up of a thick mantle of soil, blown sand, and alluvium. At each corner of this palace semi-octagonal towers were built with an elegant cupola.
