If there was a contest for the most expensive one night stand, I know of one that will hands down.
The Jehangir Mahal in Orchha was built for the state visit of Mughal emperor Jehangir by Bir Sing Deo. It has a little of over hundred rooms, airy balconies, three stories, ornate elephants, turquoise tiles imported from Turkey and a central courtyard. It took a while to build and in the end the emperor stayed at this palace for a night. The irony of it all is that is despite almost depleting his state exchequer to impress Jehangir Bir Sing soon fell out of favor with the mughals and was crushed by a teenage Aurangzeb.
