History

St. Henry was laid out in 1837 by Johann Heinrich Römer (1805–1874). It laid in a tract of land sold to him by his brother Franz on July 7, 1837. The tract was surveyed on July 7, the town was platted on July 13, and the plat was recorded on July 15. July 13 is the feast of St. Henry. At the center of the village is St. Henry's Catholic Church. Completed in 1897, the church is listed on the National Register of Historic Places. A post office has been in operation at St. Henry since 1850. The village was incorporated in 1901.
