A previously unknown section of the wall was discovered in summer 2018 in a residential section of northwest Berlin.
Several locals on a walking tour came upon a 20-meter (66-foot) section of crumbling wall, covered in graffiti, in June. The wall had been covered by overgrown bushes, which is how it had escaped discovery for so long.

So how could a section of such a massive and significant structure go unnoticed for so long?
These days, the former wall is a tourism draw.
Travelers visit the museum at Checkpoint Charlie, which was once the primary security screening point between East and West Berlin.
And there may be another tourist attraction in Berlin, if Gothe has anything to say about it — he has already filed paperwork to have the newly discovered section of the wall designated a historic site in Germany.
CNN Travel has reached out to the German embassy in the United States and will update with additional information as it becomes available.
