The Mahanandi Temple is 16km from Nandyal and about 280km south of Hyderabad. It is an ancient temple dedicated to Lord Siva. The linga is unique—a rough, uncut rock with two cavities. The priests allow you to touch the linga. There is a huge Nandi in front of the main shrine. Many people include this temple in a visit to Srisailam.
This temple is unique for South India because the vimana (tower) over the linga is built in the North Indian style. The temple’s main gate faces west. There is a tank here which is always 1.5m (5 ft) deep. The mystery is that no one knows how the water enters the tank—only that it is always the same level and crystal clear.

There is a railway station in Nandyal.
