Stewart's Folly. Listed as being built in 1973, two years before this photo but seems to have a temporary roof on it. Here it is on the Ohio Round Barn List: http://www.dalejtravis.com/barn/ohio/... Here is another story about it: https://architecturalafterlife.com/20... I can't tell if it is still there because of the trees, it is listed as abandoned. The red pin on the map marks the spot.

Here it is completed: https://vintageaerial.com/photos/ohio...

Thanks for your research on this I enjoyed reading about the building.

Burned down in March of 2016
