The hilltop fort that served as the last capital of the Vijayanagar Empire, 15 km west of Tirupati. Two palaces survive within the fort walls: the Raja Mahal (King's Palace), now an archaeological museum, and the Rani Mahal (Queen's Palace), partly ruined but with intact stucco work on the upper storeys.
The Raja Mahal Museum has a small but interesting collection — Vijayanagar coins, weapons, sculptures, and an evening sound-and-light show that retells the story of the fort. The walk up to the fort takes about 30 minutes from the parking area; the views over the surrounding hills are excellent. Combine with a Tirupati or Tirumala visit on a day with time to spare. Closed Fridays.
