In the 14 km west of Tirupathi you will find a couple of buildings that were built during the 15th century and were mostly damaged in the coming centuries. Both the Rani Mahal and Raja Mahal were constructed under Vijayanagar rule and the structure resembles Hampi Royal Centre. There is a small museum in the complex which remains open on all days except Fridays (10AM to 5PM) and fee costs you very less as Rs. 7/- for Indian and Rs. 100/- for foreigners. There is also a sound and light show which is narrated by the Bollywood stars. The buses are easily available from Tirupathi and do not charge much. You can also hire a taxi or an auto rickshaw to go there.
All days of the week except Fri 10:00 AM - 5:00 PM
