A fragmented Brahmi inscription discovered at the site names the site as "puṣpa sabhar giriya" ("flower-filled hill"), identified by the excavators as Pushpagiri. In 2000, an excavation conducted by the institute, under the supervision of archaeologist Debraj Pradhan, resulted in the discovery of a large stupa as well as several other archaeological artifacts. The artifacts included pillars, a fragmentary Brahmi inscription, terracota seals and Northern Black Polished Ware. Debraj Pradhan believed the stupa to have been erected by the Mauryan emperor Ashoka (304–232 BCE): Although Xuanzang suggests that Odra had 10 stupas erected by Ashoka, this is the only one to have been discovered so far. According to B. N. Mukherjee of Calcutta University, who deciphered the Brahmi inscription, the stupa may have been erected by "a lay Buddhist worshipper called Ashoka".
