Published in 1881, the History of Fairfield County, Connecticut, compiled by D. Hamilton Hurd, describes the early history of the Westport Methodist Episcopal Church:
The construction of the present church was commenced in the year 1851. Rev. Z. Davenport, now living at Saugatuck, Conn., was at that time the preacher in charge. Services were held in the old Universalist church for about two years, and until the Methodist Episcopal Church was completed.
[. . .] The original members were mostly persons who had in former years belonged to the same denomination and had worshiped at a church about two miles north of Westport village, at Poplar Plains.
The first Methodist sermon preached within the limits of this town was at Poplar Plain, in 1790, by Jesse Lee, in a house standing a few rods west of the now old church. Some few years after this regular preaching services were held in a ballroom of a tavern near by, and until the meeting house was built, about the year 1817, slabs upon legs being used for about forty years before the room was regularly seated. The old church is still standing, and is occasionally used upon some funeral occasion, the members having mostly died, the others having joined with some other Methoilist society.
Construction of a new church, located at 45 Church Lane, was begun in 1907. The church was known by the 1950s as the Community Methodist Church. In 1966 the church was sold to the neighboring Christ & Holy Trinity Episcopal Church, which uses it as the Christ & Holy Trinity Church Seabury Center and Preschool.
