In Jaipur and in Rajasthan, in olden days Kings and their staff have built their palaces inside the water. I really do not know the process by which they have built these palaces. for me this quiet a architectural wonders as they are still surviving despite the water around. They are called JALMAHAL, Jal means water and Mahal means palace. It means palace inside water. For me it is a wonder that a pace can survive for so many years inside the water. For me this is architectural wonder.
I was in India. The first city was Džajpur. I saw this beautiful palace on the water. It is wonderful!
