The Logan Roundhouse - aka Stewart's Folly is likely the oddest structure in the small Ohio town of Logan. The design, lacking in flat surfaces or corner, has a very low wind resistance. Concrete walls further enhance the durability to withstand extreme weather such as tornadoes or hurricanes. This building was to be a prototype for others along coastlines and Tornado Alley.
The shell construction began in 1971 and was completed in 1973. The walls are 8 inches thick at the base, and 5 inches thick in the walls. Two floors, a basement with garage, and a porch were constructed. The house was never completed, or was it ever wired for electricity.
Today it stands empty. The property is posted as "No Trespassing" - but the building can be viewed from the road easily. There is a parking area across the street that is perfect for stopping at.
