Baltimore has very little in the way of modern buildings that please the eye, but we do have quite a few very nice older buildings.
This one is the United States Custom House, a classical-style building completed in 1907. Baltimore has a number of handsome old buildings built in a similar style. In fact, enough of them that director Len Wiseman chose this part of Baltimore as a stand-in for Washington DC in his 2007 film Live Free or Die Hard. Wiseman gave us a birds-eye glimpse of the Custom House, but from the other side - you can see that side in the link above.
