Piece of World Trade Center now part of Tribune Tower.

I wonder how often the Tribune Tower on Michigan Avenue inserts these pieces of other buildings into its exterior.  This one is a jagged piece of the World Trade Center obviously from after September 11th.

Random building blocks at Chicago’s Tribune Tower on Michigan Avenue!

Obviously these stones from across the world don’t contribute to anything structurally, it’s still pretty cool to walk around Chicago’s Tribune Tower and see the dozens of pieces of history stuck into the building’s exterior.  Check out the first one!
