Hawa Mahal - Palace of the Winds - Jaipur India - built in 1798 
The top image is looking from the inside, the bottom is from across the street.
It’s five level facade represents the crown of Krishna
The lattice work in the windows is the source of the palace’s name - the small openings force the slight breeze that passes to be accelerated as it pushes through the holes. The faster moving air feels cooler. Natural air-conditioning from 200 years ago.
