St. Andrew's Episcopal Church is located at the corner of Walnut and Orchard Street in the village of Walden, New York, United States.

Babcock, who was himself an Episcopal priest, designed the building with the Ecclesiological[broken anchor] theories of Anglican church architecture in mind.

It has been renovated slightly since its construction, and joined to a nearby chapel, but remains largely intact, exemplifying those theories.

The church's main facade faces east, towards the triangle of Orchard, Scofield and Walnut streets at the center of town.

Opposite is the village's memorial to the local members of the 124th New York Volunteer Infantry Regiment, the "Orange Blossoms", who served with distinction in the Union Army during the Civil War.

[1] Three narrow Gothic lancet windows resting on a brownstone course are evenly spaced across the front, with a roundel high above.

The main entrance, at the foot of the bell tower, has double wooden doors, each with a St. Andrew's cross in the lower corner, set in a Gothic arch surrounded with three brick courses.

A louvered, recessed Gothic arch marks the bell stage of the tower, which then gives way after brief corbels to the spire, topped with another cross.

[1] The four-bay south face, looking out on Orchard Street, has a pair of lancet windows, similar to but smaller than their counterparts on the front.

[1] Like Upjohn and other Episcopal architects designing churches for that faith in the mid-19th century, Babcock was strongly influenced by articles and essays in The Ecclesiologist, a journal published by members of England's Oxford Movement, which sought a return to more traditional religious practices in Anglicanism.

Christ Church in Ballston Spa, completed by Upjohn's office after he left, also bears a resemblance, although its massing and decoration are less restrained than Babcock typically was.

[1] Congregants had moved from a primitive log cabin to a more permanent meetinghouse as the church grew, and in 1826 they decided to build a larger one in Walden, at the time an unincorporated preindustrial hamlet known mainly for its mill on the Wallkill River.

At the turn of the century the oil lamps that had originally lit the church's sanctuary were replaced with electric models, and in 1915 the rectory received its remodeled porch and some changes to the interior, such as the rear parlor fireplace.
