The Hopkinton Historical Society, founded as The Philomathic Club by three Hopkinton residents in 1859, began as a literary discussion group and was incorporated under its current name in 1875. The Society's collection of music scores, journals, diaries, books, maps, and artifacts is housed in The William H. Long Memorial Building, a gift to the Society in 1890. The Long Building is on the National Register of Historic Places.
The Society provides the greater Hopkinton community with:
- exhibits, programs, lectures, tours related to local and state history
- projects for children
- school tours
- special events such as the popular art show
- publications of local and state interest
- a library for historical and genealogical research
