Gauhar Mahal Madhya Pradesh & Chhattisgarh

This early 19th-century royal palace, chiefly associated with Qudsia Begum (r 1819–37), now stands empty, but its pretty courtyards, balconies and hallways, in a confection of Mughal, Rajput and other styles, are worth a wander. The guardian will often give you a quick tour (a tip of ₹50 is reasonable).
