With the construction of the wall in 1961, the Americans erected this checkpoint in the Friedrichstraße. Being the third checkpoint built on the borders of West Berlin, it was named Charlie, following the NATO phonetic alphabet. During the remainder of the Cold War, Checkpoint Charlie became a synonym for both separation, and - for the East Germans - freedom.
The checkpoint was dissolved after the fall of the wall in late 1989, and nothing remains of the original site. Instead, modern office buildings have been erected in recent years. The course of the former Wall is now marked on the street with a line of bricks (as in many places of Berlin). A copy of the booth and sign that once marked the border were reerected later, and a museum is located nearby.
