Checkpoint Charlie Museum

The Checkpoint Charlie Museum (German: Haus am Checkpoint Charlie or Mauermuseum) is a museum in Berlin. It is named after the famous crossing point on the Berlin Wall, and was created to document the so-called "best border security system in the world" (in the words of East German general Heinz Hoffmann). On display are the photos and related documents of successful escape attempts from East Germany, together with the escape apparatus: hot-air balloons, getaway cars, chairlifts, and a mini-U-Boat.
