A major Buddhist site has been excavated here on a hillock , known locally as Singarakonda , rising beside the Gundlakaa rivulet.

A unique double terraced stupa on the hilltop , perhaps the only one of its kind in south India , is reminiscent of the famous Dharajaka stupa at Taxila. The hude dome was embellished with 9 feet high beautifully carved limestone panels , which were adorned with symbols of the stupa , Bodhi tree and Dharmachakra .

In the vicinity , lie the ruins of a monastic complex. This comprises of a Maha Chaitya with a dome 1.6 meters high & a drum 60 cms wide , a threewinged vihara , resembling the Aparasailia monastery at Nagarjunakonda , with a pillered mandapa and two apsidal Chaityagrihas facing each other at the entrance. The vestiges of two other monasteries can also still be seen. A museum at the site houses important sculptures and other relics such as coins , black and red ware and inscriptions in the Brahmi script dating back to the century B.C.
