John Campbell was a colonel in the Ohio Militia and a land officer. He built the brick land office in 1810-1811 in Campbellsport, which is about three miles southeast of Ravenna. The area is located along what is now State Route 14 and West Branch State Park. The building is 20 feet wide and 14 feet deep. It has a fireplace and a loft.

It is said it was the first land office in the Western Reserve. During the War of 1812 the building was used as a mustering headquarters and a hospital. In early 1964 the state was acquiring land for West Branch State Park. The owner of the land where the Campbell building sat was Mr. Harry Korpita. Since he had to move because West Branch State Park was taking his land and St. Rt. 14 was being relocated, Mr. Korpita donated the building to the Society and it was moved here on March 1, 1964 by Donald Ott, a building mover from Warren, Ohio.

Some restoration was begun on the building before 1966 and additional work was done in 1971 and in 2003-2004.

The building is open for tours during regular museum hours, weather permitting.
