One of the Pres. Inaugural Balls is in a train station

Eastern Inaugural Ball at Union Station, Washington, DC: This ball is for those from Eastern states, which doesn't include New York but does include Puerto Rico and the Virgin Islands. Tickets cost $150 by invitation only.

Yes, it's a train station but a grand one that was completed in 1908. It's considered to be a Beaux-Arts wonder and was at onetime the largest train station in the world, according to its website.
