Mangalagiri is a town, and a mandal of Guntur District. The town was known to have existed since 225 B.C. This town is best known for the temple of Sri Panakala Lakshmi Narasimha Swamy. This temple is dedicated to Lord Narasimha(man-lion) and is situated on a hillock at Mangalagiri. Devotees pour “Panakam“ (Jaggery water) with a conch into the mouth of the deity. The unique feature of this temple is that the idol actually drinks the panakam and a gurgling sound is heard. However only half is accepted and the remaining half is given back, irrespective of the quantity offered. An annual festival is held in the months of August and September. This temple has the credit of being one of the eight chief holy temples (Mahakshetrams) in India.
