The First Presbyterian Society Meeting House (now the Millbury Federated Church) is an historic meeting house at 20 Main Street in Millbury, Massachusetts. The 1+1⁄2-story Greek Revival church was designed by Elias Carter and built in 1828 for a Presbyterian congregation that had been established the previous year. The main facade has a full-height portico with four columns supporting a triangular pediment. It is three bays wide, with long narrow round-arch windows in the side bays, and the main entrance in the center, topped by a half-round fanlight. The interior has retained much of its original woodwork, despite renovations in 1862 in which the main hall was reoriented from west to east.[2]
