Located in the Penobscot County town of Hampden, Maine, Harmony Hall is a facility that since 1896 has served as a public venue for civic groups associated with public advancement and education, as well as a place for entertainment. The eclectic building, which exhibits elements of Federal, Greek Revival, Gothic Revival and Queen Anne architectural styles was originally built as the Universalist Chapel in 1829 and substantially renovated for use as a social meeting hall by the Village Improvement Society in 1895/6. The Village Improvement Society was the first of several, female-centered organizations associated with the Hall that focused on a progressive agenda during the last years of the 19th century and the early 20th century. Designated as a local landmark by the Hampden Historic Preservation Commission in 1993 for its association with local womens? organizations, the building derives National Register of Historic Places significance under Criterion A, for social history, from its association with the Village Improvement Society, the Dorothea Dix Memorial Association, the Hampden Garden Club, and its use by the local Suffragists.
