The Wellesley Town Hall presents an ornate and regal exterior to the public from its perch atop a high hill on Washington Street. The stone, castle-like building has been on the National Register of Historic Places since 1976. Within, the building houses many town offices, including departments for Selectmen, Assessors, Building, Financial Services, Natural Resources Commission, Network and Information Services, Planning, Town Clerk, Treasurer/Collector and Veterans Services. The grounds of the building are part of Hunnewell Park, which includes a wide expanse of lawn, many trees, picnic tables and benches.
