The East Side Gallery is the name for a 0.8 mile (1.3 km) stretch of the Berlin Wall that has been covered with murals. The paintings were completed as a monument to freedom of expression in 1990, the year after the wall fell, by artists from around the world. It’s considered one of the largest open-air galleries in the world, with several murals becoming individually famous for their political commentary. The East Side Gallery is free to visit, but several local guides and artists offer tours of the wall which are highly recommended for visitors who want to learn more about the Berlin Wall and the paintings presented on its remains.
