St. Andrew's Church is a historic Roman Catholic church in LeRoy, Wisconsin, United States. The Gothic Revival church was designed by architect Anton Dohmen and built 1899–1901, largely by parishioners.[1] The Emil Frei Stained Glass Company later added over 20 stained glass windows to the church; these windows were described as "works of art with vivid colors and intricate details" by the Wisconsin Historical Society.[2] The church's congregation was composed of German farmers from the surrounding area, who paid for the church and constructed parts of its interior; the church has historically served as a focal point for community life. The church has been called the "Cathedral on the Marsh" due to its proximity to the Horicon Marsh.[2] On January 27, 2010, the church was added to the National Register of Historic Places.
