The Hyson Schoolhouse is a single-roomed stone structure measuring 24 feet by 26 feet. It was possibly built by Archibald Hyson, a local landowner and carpenter. The schoolhouse was converted to a private residence when a new schoolhouse was built across the street in 1892.
Dendrochronological analysis has shown that the original structure was built in the summer of 1857 or shortly thereafter.
