Built in 1910, this church is home to an active Catholic parish, and it has been declared a historic site because of its well-preserved Romanesque Revival architecture.

One of the first two Catholic priests in northern Ohio was John William Horstmann, a native of Osnabrück who had settled in the village of Glandorf to the north.

[4] By 1839, the Catholic community in Wapakoneta had grown to the point that it could be created a separate parish,[5] and the members built a small frame church on the southeastern corner of the intersection of Pearl and Blackhoof Streets near the city's downtown.

Although no resident pastor served the parish in its earliest years, membership grew during the 1840s and 1850s, and a priest was first assigned to the church in 1857.

The expenses of maintaining even a small church caused the parish to be deep in debt during its earliest years, but it prospered greatly under the pastorate of Joseph Gregory Dwenger, later Bishop of Fort Wayne.

In later years, elderly parishioners remembered the organ and bells favorably: purchased for $2,200 and $1,700 respectively, they were seen as equal to any instruments of the twentieth century and as worthy of installation in the present church building respectively.
