al Mahal (meaning "Water Palace") is a palace located in the middle of the Man Sagar Lake in Jaipur city. The palace and the lake around it were renovated and enlarged in the 18th century by Maharaja Jai Singh II of Amber. The Jal Mahal palace is considered an architectural beauty built in the Rajput and Mughal styles of architecture (common in Rajasthan) providing a picturesque view of the lake, and the surrounding Nahargarh (abode of the tigers) hills. The palace, built in red sandstone, is a five storied building out of which four floors remain under water when the lake is full and the top floor is exposed. The rectangular Chhatri on the roof is of the Bengal type. The chhatris on the four corners are octagonal.
