I walked around the Diag a bit, so I took some more pictures.
A shot as you are looking towards the Diag from the Bell Tower.
A shot of the Michigan League building near the Bell Tower.
A wider shot of that building.
One of the Diag Archways.
A close up of that archway.
A symbol on the sidewalk of the archway. NOt sure what it is. I think it is a mason symbol.
