The two temples facing the Agastya lake, are known as the Bhuthanatha group of temples. To the east of the lake is the Bhuthanatha Temple and the temple to the North-East is the Mallikarjuna Temple. Built of local sandstone, they are dedicated to Lord Shiva, in the form of Bhuthanatha. The architecture resembles a typical South Indian temple. The sandstone used to build these temples gives them a beautiful glittering tint in the afternoon sun.
