The Keshava temple at Somanathapura faces east and is enclosed in a walled courtyard with a major gate ("mahadvara"). Outside the walls before the gate stands a tall pillar, which once had a Garuda statue on top, now missing. Inside the gate, to the left are vertical standing inscription stones. These stones have the form of the hero stones, with the top decorated with Hindu iconography as well as miniature reliefs of Keshava, Janardhana and Venugopala. The inscription is in old Kannada. The small entrance mandapa is supported by lathe-carved soapstone pillars. The temple is carved from soapstone, a green-grey chloritic schist material that is soft in quarry but hardens when exposed to air. This is not locally available and must have been imported from another part of South India. It enabled the artists to shape and carve out intricate details for the artwork.
