The original Union Station, listed on the National Register of Historic Places, has been adapted as a character-laden hotel. As such, it's not necessarily open to touring, but the starting point of the Indianapolis Railroad is worth browsing nevertheless. Trains still run through the Romanesque Revival property, offering a glimpse of yesteryear, and the renovation of the station is a feast for the eyes. The Grand Hall boasts works of art, stained-glass windows, and barrel-vaulted ceilings. A great glimpse of the city's past.
