40th parallel passes through the main campus of The Ohio State University; specifically, it cuts directly across the Oval greenspace, between University Hall and the William Oxley Thompson Memorial Library. Ohio Stadium, one of the largest stadiums in the world, barely misses the parallel 40° north (6 seconds above 40° north).
The benchmark was originally set in 1881 by the two members of the first faculty of Ohio State, T.C. Mendehall, Professor of Physics, and R.W. McFarland, Professor of Mathematics and Astronomy. Two of the academic buildings nearby are named after them.
A plaque just north of Thompson Library marks the 40th parallel.
