In 1916, the building known earlier as the Town House was equipped with complete facilities for theatrical productions, including stage, curtain, lighting and a stage set designed by Maxfield Parrish. This was all contributed by William Howard Hart, a distinguished New York stage designer and artist who summered in Plainfield for many years during the Cornish Art Colony era. Throughout New England, Plainfield had the reputation of having "the most beautiful stage north of Boston"1
Over the years, a variety of town activities have taken place in the Town Hall including plays, dances, movies, bingo, fund raisers, historical society meetings, basketball games, variety nights, library programs, rummage sales, concerts, art shows, bicentennial celebrations, town meetings and even rifle practice.
The Plainfield Town Hall was placed on the National Register of Historic Places in 1985. It is also included on the National List of Historic Theater Buildings. The Town Hall's renovations were completed in 1995.
