The Moosup United Methodist Church is at 13 South Main Street in Plainfield. As related in the Plainfield Bicentennial, A Souvenir Volume (1899):
The Methodist Episcopal Church in Plainfield began its history in 1825, when it was included in the Norwich circuit, though, before 1800, preachers were sent here and occasional services were held. At first, the church met in the old Separate meeting-house on the corner near Evergreen cemetery for occasional services […] [A revival occurred in 1843 and] That same year they purchased of the Separatists, or their successors, the old meeting-house which had been removed to Union Village. A new church was built in 1871, a little further up the river and was dedicated, February 1, 1872.
As related in Vol II of the Souvenir history of the New England Southern Conference (1897):
The church in which the people now worship is in the very centre of the village, and pleasantly situated. It was built in 1870 by the arduous labors of Rev. Lewis E. Dunham, and marked a new era in the prosperity of the society. In 1882, during the pastorate of E. J. Ayres, the building was raised, and a vestry provided in the basement. The interior of the church has recently (1896) been thoroughly repaired, a steel ceiling and chancel introduced, making it a most attractive and inviting place of worship. The parsonage, one of the most convenient and commodious, stands on the lot adjoining the church. It was built during the pastorate of the Rev. W. W. Ellis of sainted memory.
The church was completely remodeled and rededicated in 1908.
