A cross between Harry Potter's Hogwarts and a Scottish baronial castle, this 1888 pile was the official summer residence of the British viceroys until WWII and the scene of two crucial conferences (1945 and 1946) that essentially sealed the partition of India. To look inside join a group (departing every 45 minutes from the cafe/ticket booth) for 20 minutes perusing three rooms of historic photos. Then exit through the superb three-storey entrance hall that looks like an MC Escher design built in Burmese teak.
