German Technical Museum

Dedicated to transportation, manufacturing and technology, the museum boasts an impressive array of radios, phones, planes, sea-faring vessels and two whole locomotive sheds on its sprawling campus.

In this, Berlin’s newest museum, visitors are taken on a historical journey covering the highlights of a geek history that started 60 years ago.

There are about 800 exhibits presented in a permanent exhibition, and those that are still playable are played regularly.

For fans of public transportation, there is no better place to get this history of Berlin’s amazing subway than this museum, with historic signal boxes, train cars and much more.

This research and memorial center concerns the political system of the former East Germany, and is held in the former ministry for state security. This is for the geeks who like to be creeped out.Photo credit: Andreas Praefcke

Best seen on a bike (it’s about the size of Central Park), the former Tempelhof airport now serves as a park—complete with runways and access roads, right in the middle of the city.

The dome atop the German parliament, designed by architect Norman Foster, offers visitors a free, 360-degree view of the city as they spiral up inside of it.

Berlin’s most visible landmark, this TV tower rises 1,207 feet above Alexanderplatz. Visibility can reach 26 miles from the observation platform mid-sphere on a clear day. Oh, there’s a revolving restaurant up there, too.

If a museum isn’t enough for you, experience the U-Bahn system with a first-hand tour through the city’s tunnels—yellow hard hat required.
