The people of the church started meeting together around 1870
, when Archie Mullen started a Sunday School in a small rural Wisconsin town called Keystone. This is now the township of Cleveland in rural Cornell, Wisconsin.
Meetings were held in homes until 1885
. Then people met together in the first Cleveland Center School. Rev. Priddy of Bloomer and Rev. Hulbert of Turtle Lake assisted in organizing a church.
The people's labor came to fruition with the building of the First Congregational Church on June 12, 1893.
The building was located at the intersection of county roads E and Z in the township of Cleveland, Wisconsin.
The church has been meeting continuously from 1893 to present except for a brief period in the mid-1930's when it was closed. Keystone was a Congregational church from 1893 until the mid 1930's.
- The church was re-opened as part of the Wisconsin Rural Missions Church.
- Keystone joined the Christian and Missionary Alliance denomination.
- A log church was built four miles down the road (24288 County Highway Z)
from the original site.
2000 - An addition was added to the church for Sunday School rooms and offices.
