The Town Hall was built in 1904. It was named after the current mayor, J. H. MacNaughten ("Johnny Mac"), who had donated the land on which to build it for one dollar. The building cost an additional 2669 dollars. An air raid siren was installed in the cupola during the 1950s to warn of an attack from the Soviet Union, used only as a curfew call - sounding at 9 p.m. - during the 1950s and early 1960s, and removed in the 1980s. The building has served also as a movie theatre, as a "community centre" for dancing and card-playing, as an art gallery for local artists, and as the village jail. Eleven full-time employees work in the Town Hall serving the needs of the 5200+ population of Hudson.
