Jal Mahal - Jaipur, India

Jal Mahal (Water Palace in English) is set in the middle of Man Sagar Lake. The reservoir was built in 1596 and while only one storey shows in the image, there are four other levels hidden beneath the water. The building was initially intended to be a hunting lodge for the local Raja. However, when a drought hit in the 16th century, locals created a dam, which formed a lake around the building. While inaccessible to visitors, the views from the land are spectacular, especially in the evenings.
