St. John the Baptist Catholic Church is a prominent building in Johnsburg. It is listed on the National Register of Historic Places as number 80000137.
The congregation was founded by six families in 1841. When built in 1842, the church was the first in the approximately 100 miles (160 kilometers) between Milwaukee and Green Bay. Named after the church, St. Johannes Gemeinde (St. John's congregation), the community was known as Hinesburg.[3] Father Deisenrieder had a post office established and the town received its original name to honor his birthplace in Bavaria.[4] The United States Postal Service changed their methods in 1885 and the community was renamed "Johnsburg".[5]
