The historic “Gatabaruwa Rajamaha Viharaya” and the temple of god “Rajjuru Bandara” are located on the Gatabaru hill, 1500 feet above sea level, on the Galle-Deniyaya road at the village of kotapola in the Kotapola division, Matara District of Sri Lanka.
The Gatabaru cave temple is placed in a very scenic environment between the Rakwana mountain range, the Singharaja mountain range and the Morawaka range, rising above many smaller mountains that surround it. It is attached to the Diyadawa forest and lies 2 km from the Kotapola town
A 30 feet cave on the top of the hill gives sanctuary to a large statue of Lord Buddha in the sleeping state with a statue of Mugalan Thero at His feet and a statue of Sariuth Thera at the side of His head. On the two sides of the Statue are built, a temple of god Rajjuru Bandara and a temple of gods Vishnu and Katharagama.
