Hawa Maha:

Jaipur's most acclaimed landmark, the tapering Hawa Mahal, commonly known as "Palace of Winds", was built in 1799 to enable the women of the court to watch street processions while them not being seen by others. Its five story building has 593 finely screened windows and balconies however the depth is only little more than one room in most parts.

Here we really needed a serious wide angle lens.
