Temple of Nageswara Swamy
A historical temple of Nageswara Swamy buried in sand was unearthed at Perumallapadu, near Chejerla, in Nellore district. The temple, which according to the legend was consecrated by Lord Parasurama, an avatar of Lord Vishnu, got buried over a long period of time as river Penna changed its course.
In about 1850 AD, the village was rendered unlivable, because of the nearby Penna river rising often and kept flooding the village frequently. When everyone was fed up with the damaged it caused to their homes and fields, moved away, and slowly the sand dunes engulfed the whole temple. And when it was accidently discovered, and as the sand was slowly removed, the magnificent temple slowly emerged in full glory after decades of being covered and hidden by mud and sand over a period of time.
