Nallamalla
The Nallamala Hills extend between the Krishna and Pennar rivers, forming a long section of the Eastern Ghats. Forested ridges and gorges shelter sacred places such as Ahobilam, where temples honour Narasimha, the lion-headed form of Vishnu. Its shrines received gifts from the Kakatiya and Reddi dynasties and later from the rulers of Vijayanagara; Krishnadevaraya visited them in the sixteenth century.
