St. Augustine's Catholic Church is a historic church in Napoleon, Ohio, United States. Located on the edge of the city's downtown, two blocks away from the Henry County Courthouse, the church is a prominent landmark in Napoleon.HistorySt. Augustine Parish was founded at some point between 1856 and 1858; its first priest was Michael Pietz. The parish was dedicated to St. Augustine in honor of Augustine Pilliod, who supervised the construction of its first building. This structure was replaced with the current church, which was built at a cost of $21,893; although construction was largely completed in 1881, the altars were not installed until 1888.ArchitectureSt. Augustine's Church has been rated a fine example of Gothic Revival architecture: both its exterior and its interior feature many examples of the style. A high ceiling, supported by many Gothic arches, rises above the sanctuary and its elaborate wooden altar and pews. Stained glass windows on the front, rear, and sides of the church provide light to the interior. The building's exterior, topped with a steeple that rises above the ground, is built of brick trimmed with stone. The entire structure rests on a stone foundation; at the time of construction, small windows lit the basement, but these windows have since been closed with concrete blocks. Other small alterations have been made to the building over the years, including the replacement of the original front doors and wooden steps and the removal of crosses on the building's corners.
