It was one of Europe's biggest symbols of division, but years later, the Berlin Wall is bringing protesters together to fight developers who want to knock part of what remains down.
After dividing the east and west of the city for 28 years the wall officially came down in November 1989.
Two sections of the wall were left standing and in 1990 a 1.3 kilometre stretch was decorated with murals - known as the East Side Gallery.
Developers now want to remove a 22 metre stretch of the gallery to make way for new apartments and a footbridge.
