A watch tower located in the south-eastern corner measures 11.5 * 10.55 m.[2] Ancient pottery, beads, bricks querns, and other artifacts have been found at the site.

Some scholars such as A. M. Sastry and K. D. Bajpai have identified the issuer of these coins with Simuka, who is considered as the founder of the Satavahana dynasty based on the Puranic genealogies.

However, the discovery of coins at Kotilingala and other sites in present-day Andhra Pradesh and Telangana has prompted some historians such as M. Rama Rao to theorize that the eastern Deccan was also a part of the early Satavahana territory.
