Tribune Tower

Colonel Robert McCormick, eccentric owner of the Chicago Tribune, collected – and asked his reporters to send – rocks from famous buildings and monuments around the world. He stockpiled pieces of the Taj Mahal, Westminster Abbey, the Great Pyramid and 120 or so others, which are now embedded around the tower’s base. And the tradition continues: a twisted piece from the World Trade Center wreckage was added recently. The unusual ‘bricks’ are all marked and viewable from street level.
