The smaller hill known locally as Chikkabetta rises about 175 feet above the plain and is 3,052 ft above the level of the sea. In the old inscriptions it is designated as Katavapra in Sanskrit and as Kalvappu or Kalbappu in Kannada. A portion of this hill is known as Tirthagiri and Rishigiri. With the exception of one shrine, all the basadis on the hill are enclosed in a walled fort area. Almost all the temples are built in the Dravidian style of architecture, the oldest of them going back probably to the eighth century A.D. Altogether the number of the temples in the walled fort area is fourteen and their plans are mostly similar to one another.

The history of this hillock dates back to 2nd Century B.C. and has a history that is 1000 years older than that of Indragiri. We can find many inscriptions spread across the hillock. These inscriptions help us understand the antiquity of Jainism and Shravanabelagola.
