In Anegundi stands the regal palace, Gagan Mahal, which belonged to the rulers of the Vijayanagara empire. Also, know as the Old Palace, the charming building is believed to have been constructed in the 16th century. Designed in an Indo-Islamic architectural style, the yellow-ochre palace is a sight to behold. With four towers, decorated balconies and protruding arched windows, the palace, locals say, was constructed as a residence for queens and other royal family members. It also had a pool and a smart water drainage system, which was used to keep it cool during summer. Though most parts of the palace are in ruins today, some have managed to survive and offer glimpses of the magnificence of the buildings in its heydays.
