The Auglaize County Historical Society Wapakoneta Museum Is housed in the original First Presbyterian Church built in 1861-1862. It is achitecturally significant as the only example of the distyle in antis mode of Greek Revival artchitecture in an eight-county area of west-central Ohio (so named because of the placement of paired columns within the recessed front entrance).
It is historically significant because of its association with the early Auglaize County's most politically influential citizens. The structure is the oldest extant church building in Wapakoneta and the oldest Protestant Church in Auglaize County. The congregation was incorporated as the First Presbyterian Church of Wapakoneta in 1860.
The congregation was rocked by financial scandal, causing membership to fall from 264 in 1922 to 20 in 1930. The church dissolved in late 1930 and its trustees sold the building and its contents.
Mrs. Ida Wintzer purchased the building and presented it to the Wapakoneta Women's Club for $1.00. The Women's Club met there until 1997 when the property was sold to the Auglaize County Historical Society.
The First Presbyterian Church of Wapakoneta was listed on the National Register of Historic Places in 1985.
Today the building is home to historical items from Wapakoneta and Auglaize County.
