Mount Zion Methodist Church is located on Primrose Avenue (NY 139) in Somers, New York, United States.

The church building is located on a small 1.4-acre (5,700 m2) lot along the east side of Primrose just south of Reis Park.

[1] It is a two-and-half-story post-and-beam frame gabled church 30 by 40 feet (9.1 by 12.2 m) on a slightly exposed fieldstone foundation.

The roof is shingled in asphalt and has an overhanging eave, complemented by plain frieze and cornerboard.

The main entrance, in the middle of the south (front) facade, is a pair of doors with a shouldered architrave surround.

The walls are wainscoted with vertical beaded tongue-and-groove boards on the first story, and plain white plaster above.

A balustered wooden communion railing along the front also curves to slightly cover the sides.

A small group from the Civil War period are the most ornate in the cemetery, adding books and chain-and-tassel designs to the earlier flourishes.

Prior to the establishment of churches, the denomination's preachers traveled in "circuits", groups of towns where they had gained followings.

[1] In 1787, the New Rochelle Circuit was formally established by Freeborn Garrettson at the direction of Bishop Francis Asbury.

Asbury had declared that all Methodist houses of worship were to be "plain and decent, but no more expensive than absolutely unavoidable."

Zion, resembling houses or barns more than churches, with only their large windows suggesting that use and the influence of the Federal style.

Zion's regional influence continued on churches in the rural communities to the north and east until 1861, when the circuit was effectively disestablished.

The construction of the New York City water supply system in northern Westchester ended that resurgence, as the land acquired for its reservoirs displaced many of the local farmers who had made up the bulk of the congregation since its earliest days.

[1] The church building went under the care of the Methodist congregation in nearby Katonah, which maintained it for a while in the early 20th century and held anniversary services there once a year.
