Metro Center Station, Washington D.C.
America isn’t exactly known for having a great subway system, let alone architecturally impressive stations – it’s all pretty utilitarian – but Metro Center Station in Washington, D.C. is a notable exception.

Pyongyang Metro, North Korea
The old East German subway cars (complete with their original German graffiti) aren’t the only curious sight at the Pyongyang metro station in North Korea; it’s also full of propaganda murals. Foreign visitors can’t ride the metro – if you manage to take a trip to this reclusive communist nation, you’ll have to see it on an official tour.
Arts et Metiers, Paris
Located just under the Musee des Arts et Metiers (the Arts and Crafts Museum) in Paris is this cool station, reminiscent of a submarine with copper walls and porthole-like windows.
