The Iron County Fair Opens Today, Like It Has Since 1896. Its Octagon Hall Was Built in 1931 and May Be the Last of Its Kind in Michigan.

The Iron County Fair opens today, Thursday, August 27, at the fairgrounds on West Franklin Street in Iron River, and runs through Sunday the 30th. There is no gate fee. You pay $5 to park for the day, or $10 for a season pass, and walk in. The demolition derby is Saturday at 6, the mud bogs Friday at 5, the market livestock auction Friday at 6, and the horse speed events start Saturday morning at 9. Livestock judging is Friday from 9. Entry day, when the 4-H kids bring the animals and the exhibits in, is Wednesday.

The fair says it has been a staple of the county since 1896, and it is easy to walk through it without looking at the one building that makes this particular fairgrounds different from every other one in the state.

It is the exhibition hall, and it is an octagon. Eight sides, two stories, a steep hipped roof coming to a point, and three single-story wings radiating off it, all of it built of concrete block set in red mortar, with wooden shutters over the windows. It was designed by David E. Anderson and put up in 1931, which is to say in the second year of the Depression, by a county whose iron mines were the reason it existed and were about to go very quiet.

The polygonal exhibition hall was a type. County fairs across the Midwest built round and many-sided halls in the late nineteenth and early twentieth centuries because the shape did something useful: exhibits could be laid out around a central space and a crowd could move through them in a loop, seeing everything, ending up back where it started. Then the type went out of fashion. When the National Register listed the Iron River hall in 1983, the nomination called it perhaps the final example of the polygonal county fair exhibition building built in Michigan. Not the last one standing. The last one built.

That is a small distinction and it matters here. Iron County was still building things for its fair in 1931, when a lot of places had stopped building anything. Whatever else the octagon is, it is a county deciding, in a hard year, that the fair would go on and deserved a proper building.

It still does what it was built for. Walk in Thursday and the exhibits will be laid out around the middle of the room the way they were meant to be, and you can go around them in a circle and come out where you went in.
