I was born in New York, and have lived many, many other places, so i am not from Ohio.
When i was living in Columbus, Ohio, though, the Greek community built the Annunciation Greek Orthodox Cathedral. It includes more than one million bricks, and i was able to watch its construction over the years. Even these lovely pictures don't really do it justice . . .
I also liked the old Greek Orthodox Church which had stood on Park Street, where you see the parking lot in the second picture, but which, sadly, was torn down when the other had been built.
