The picture above was taken by Mound Photographers about 1930. At this time the Blue Hole Restaurant was on Route 269 in the heart of Castalia, where Kuns Family Medicine is now located. A Fleet Wing service station was on the south side of the street. Note that the street is made of bricks. At the top of the Blue Hole Restaurant building is a sign indicating that the entrance to the Blue Hole is only 2000 feet away. A long time tourist attraction, the Blue Hole is now privately owned and closed to the general public. You can read more about the Blue Hole and Margaretta Township in Glenn Kuebeler’s book Castalia, Cold Creek, and the Blue Hole.
