What was the Berlin Wall’s longest remaining open-air gallery called?

The Berlin Wall’s longest remaining open-air gallery is called the East Side Gallery.

The East Side Gallery occupies a roughly 1.3-kilometre section of the former wall along the Spree River in Friedrichshain. More than 100 artists painted murals there in 1990, shortly after the border opened. The works address freedom, political change, peace, and the experience of division.

Unlike many earlier wall paintings, these murals were made on the eastern side of the former barrier after the political system had changed. The gallery includes Dmitri Vrubel’s famous fraternal-kiss image and Birgit Kinder’s Trabant breaking through the wall.

The site is both an art destination and a preserved historical remnant. Restoration has been necessary because paint, weather, pollution, construction, and vandalism damaged the murals. The gallery is often called the longest open-air gallery in the world, though its central historical fact is its location on a surviving Berlin Wall segment.
