Key Tower is actually a bank and headquarters to Key Bank. It is an historic building initially called Society Bank. Society's funds quadrupled during the Civil War, it erected its own office building on the northeast corner of PUBLIC SQUARE in 1867. The cornerstone and lamp light are still there outside. When you go in there is plenty of marble, carved wood, art and stained glass (probably Tiffany glass as Tiffany had their building not far from this one) from that era. It's a beautiful building to walk through and see. read more
