Union Station

Constructed in 1914, this Union Station was known as the third largest train hub in the country, right behind New York's Grand Central and Pennsylvania stations. It has since lost this distinction, yet it remains one of the popular city attractions; the station has been newly renovated and is even more resplendent with its grandiose high ceilings, arched windows, theaters, exciting touring exhibitions and the beloved Science City museum. Other than the architectural eye candy, there is plenty to do inside the station - browse through shops or eat at one of the many fine restaurants.
