Housed in the Romanesque Gothic former Union Station railway terminal (built in 1900), this hotel is a grandly restored National Historic Landmark following a $16 million renovation in 2007, and a $15.5-million room renovation in 2023. It’s part of the boutique Autograph Collection by Marriott, which means contemporary amenities amid all the opulence. The lobby is the former main hall of the railway station and has a vaulted ceiling of Tiffany stained glass that, in combination with the ornate chandeliers, is simply breathtaking—and makes an ideal stop for a coffee or cocktail at the lobby bar. Warm light streams through the stained glass of the barrel-vaulted ceiling, even when it’s raining outside. Guest rooms offer exterior views, but the in-room details are noteworthy, with ceilings inspired by Pullman carriage cars and antique burnished brass that echoes the hotel’s art-deco style. Naturally, the luxe room upgrades have resulted in higher rates, but if you’re a history, railway, or architecture buff, Union Station is a must-see and (possibly) a must-stay.
