According to the Village of Ossining Downtown Walking Tour:

The United Methodist Church, located at 1 Emwilton Place and constructed from 1877 to 1885, was built to house the Sing Sing Methodist Congregation and was originally known as the Sing Sing Union Chapel. It is one of a number of High Victorian Gothic churches in Ossining. A chief sponsor of the new church’s construction was Henry J. Baker, who built the nearby Highland Cottage. Baker helped raise $30,000 toward the church but died in 1878, a year after the start of construction. Baker’s passing, the lack of funds and higher than expected construction costs delayed completion of the building, which sat unfinished for eight years until finally completed in 1885. The structure features windows created by the Tiffany Glass and Decorating Company of New York City.
