Jaipur- Hawa Mahal (Palace of Winds)

The structure was built in 1799 by Maharaja Sawai Pratap Singh designed by Lal Chand Ustad in the form of the crown of Krishna, the Hindu god. Its unique five-storey exterior is akin to the honeycomb of a beehive with its 953 small windows called jharokhas decorated with intricate latticework. The original intention of the lattice was to allow royal ladies to observe everyday life in the street below without being seen, since they had to obey strict "purdah" (face cover). The lattice also allows cool air from the Venturi effect (doctor breeze) through the intricate pattern, air conditioning the whole area during the high temperatures in summers. (Wikipedia).
