This stone basin was discovered at the site of Bomunsa Temple, which was named thus following the discovery of a fragment of tile inscribed with the name 'Bomun.' The site contains traces of a main Buddhist hall and twin pagodas, as well as well-preserved two flagpole supports and a pedestal for a stone lantern.
This flat-bottomed stone basin, which was used as a water container at the temple, is very similar to those still used at temples today. It is made from a single piece of stone hollowed out to hold water.
Considering the style of this large unsophisticated basin and other nearby relics, it is thought to have been made during the Unified Silla Period (668-935).
