Asa Munn opened a mercantile business in the community circa 1817.
In 1990 the village received national media attention and interviews by Connie Chung when a local dairy farmer, Delbert Ward, allegedly murdered his brother William Ward by suffocation.[2] Delbert was found not guilty at trial. In 1992, this incident was examined in the documentary Brother's Keeper.
Munnsville became a popular racing location for skateboarding because of the Madison County Gravity Festival, which began in 2002. Skateboarders from all over North America and Europe descend on the town for the last weekend of July and race their skateboards at speeds up to 95 km/h.
The former Munnsville depot of the defunct (March 29, 1957) New York, Ontario & Western Railway is now a private residence, occupied by NYO&W historian and author John Taibi.[3]
