One of the most incredible interior spaces in Chicago is rarely seen, unless you are a commuter or Amtrak loyalist.  And even then, most people rushing to or from their train have little time to stop and admire the breathtaking architecture surrounding them.  Union Station was completed in 1925 by the architectural firm of  Graham, Anderson and Probst, though Daniel Burnham drew up the original plans; he died before his plan could be realized.  The 110’ high, block-long Great Hall is a vast space defined by it’s barrel-vaulted ceiling and rows of Corinthian columns (not related to the Corinthian leather in your dad’s Chrysler).  As many as 100,000 passed through Union Station back in its heydey in the 1940s, though today it’s a small fraction of that number.  Next time you are in the west Loop, grab a sandwich and have lunch sitting on the benches in the Great Hall and just admire how grand architecture can inspire the soul–or at least make for an enjoyable lunch.
