Identified by A. Cunningham with Kiu-pi-shwang-na of Hiuen Tsang, which is rendered into Sanskrit as Govisana Julien Krishna Deva of the ASI excavated the site in 1939-40 and again in 1965-6 and 1970-01.

The original structure, first noticed by Cunningham ( Phase I), apparently consisted of only a lofty platform, with two recesses. Later (phase II) the platform was encircled by a 1.85 m wide and 6 m high wall, when theintervening space served as the pradashinapatha. Finally in Phase 3 the east end was widened and another enclosure wall thrown around the extended layout, adding square platforms at the comers, and thus converting the entire complex into temple of panchayatana order.
