Chittorgarh
Visit the palace of the legendary Queen Padmini on a small island in the fort's reservoir — it was from this palace's mirror that Alauddin Khilji is said to have first glimpsed her reflection, setting off the siege of Chittorgarh. The setting, with the lake, palace, and fort walls, is impossibly romantic.
The mirrored room said to have shown Padmini's reflection is no longer there, but the setting tells the story powerfully.
