Sisaniya is an important archaeological site with an ancient mound. The site is believed to have had an ancient stupa and a Sangharama built by the Sakyas. Prof. Giovanni Verardi, the Director of 1993-94 Nepalese and Italian joint investigation team mentions existence of an important craft center of Kusana period in Sisaniya. His conclusions are based on the evidences found during the excavation, for instance, iron slogs and glass wastes during the investigation. Other artifacts found during the excavation include wares and terra-cotta figurines of Kusana Period.
