Built in 1889, this building served as Milltown School No. 78 until 1908, when the Milltown Public School was built on West Church Street. After the school moved, the structure became the Milltown Municipal Building and Court Room, and in 1911 it was renovated to house the newly formed Fire Department as well. The municipal offices and court moved to a new location in 1956, but Eureka Engine Company No. 1 of the Milltown Fire Department continues to operate from the building. Though the cupola is gone and an addition has been made, the firehouse still looks much as it did in 1889, and the original blackboards from its school days are still used to log fire calls. It played an important role in Milltown's history by serving crucial community functions, and it is the oldest structure in Middlesex County housing an active and functioning Fire Department.
