The church was built on Ogilby's summer estate in Briarcliff Manor. Richard Upjohn designed the church building, which was constructed from 1848 to 1854 and expanded in 1911. The church has several memorial windows, including one by John LaFarge and a rose window by Frederick Wilson of Tiffany Studios.
