This helmet was discovered in the mud flat under the revetment to the east of the pond. On the top is a hemispheric cover with two holes for attaching decorations. The upper part was made of two concave iron sheets, which were bound and fixed with round-headed nails. In addition, iron scales were also excavated, which seem to have been linked through the holes in the lower part of the helmet to cover the wearer’s neck and shoulders. This is the only extant helmet from Unified Silla.
