After Congregationalism ceased to be the official religion of Massachusetts and the church could no longer also function as the town house, Sturbridge built its first secular Town Hall in 1838. Twenty years later, the town allowed the Worcester South Agricultural Society to add a second floor for its activities, including the annual Sturbridge Fair. As the need for public space grew, the town later purchased its tenant's interest. Reflecting the Greek Revival style that cast public buildings as temples of democracy, pillars and a portico were added to the plain front in 1910, and the Town Hall was renovated a century later.
