For most visitors to Berlin, Checkpoint Charlie is a 'must see', though the reality is usually not what most tourists had been expecting. This free open-air exhibition, located right next to former Checkpoint Charlie, provides information on the legendary border crossing with the aid of 175 large-format photos and bilingual texts. Until 31 December.

Checkpoint Charlie, Friedrichstraße, www.bfgg.de/projekte/checkpoint-gallery.html. Open 24hrs.
