Anyone that has driven through Cleveland has seen this building. It is a huge block of concrete, once used to create blocks of ice for the shipping industry before refrigeration became possible. Inside it rots. But everyone sees it's advertising space from I-90, giant painted billboards on it's sides. I never thought it could be so rotten on the inside. It's due to be torn down to make way for a new bridge; but not without legal battle.
Looks like a photographer did some exploring, and found some very interesting shots of the decay within.
