Udayagiri
Udayagiri lies in the hill country of Andhra, where a fortress occupies a commanding height above the surrounding settlement. Its position made it an important stronghold on the eastern frontier of the Vijayanagara kingdom.
The fort was held by the Gajapati rulers before Krishnadevaraya of Vijayanagara besieged and captured it in the early sixteenth century. Later it passed to Golconda chiefs and the Nawabs of Arcot.
