St. Mary's Episcopal Church is a historicchurch at 115 S. Main Street in Monticello, Arkansas. The modest 1+1⁄2-story wood-frame Gothic Revival structure was built in 1906. When built it had a castellated tower, but this was removed at an unknown date. Because of declining participation, the Episcopal Church sold it in 1938 to Victor Borchardt, who operated a radio and appliance repair business there, making numerous alterations to the building. Changes made included the removal of Gothic-style lancet windows, a gabled front porch, and the introduction of a mezzanine and second floor in portions of the building.
