Sri Veda Narayanaswami Temple is located in Nagalapuram, 70 km south-east of Tirupati.
It is believed that Lord Sri Maha Vishnu, in the form of Matsya, killed the rakshasa (demon) Somakudu here, and retrieved the Vedas from the latter.
The sanctum sanctorium houses an image of the Matsya form of Vishnu, with Sridevi and Bhudevi on either side. A peculiar feature of the idol is that it holds the Sudarsana Chakra in prayoga (ready for release).
The temple was constructed by Sri Krishnadeva Raya, the Vijayanagara emperor, and is a fine specimen of the Vijayanagara style of architecture.
The sub-temples within the main temple are:
* Sri Vedavalli Tayaru
