1878 – Bahnhof Alexanderplatz, Berlin, Germany

Horribly clad on the exterior, this station on the S-Bahn still has its original 19th century heart. Originally designed by Johann Eduard Jacobsthal, it was reconstructed by Hans Joachim May before further additions made during the era of East Germany. Like other stations on the S-Bahn, it has a fine iron structure covering the elevated platforms.
