The East Side Gallery memorial in Berlin-Friedrichshain is a permanent open-air gallery on the longest surviving section of the Berlin Wall on Mühlenstraße between Berlin Ostbahnhof and the Oberbaum Bridge along the Spree. In the spring of 1990, after the opening of the Berlin Wall, this section was painted by 118 artists from 21 countries over a length of 1316 meters. The artists commented on the political changes of 1989/90 in a good one hundred paintings on the side of the wall that used to face East Berlin, using a wide variety of artistic means. Due to urban planning measures, it is no longer preserved in its entirety, and instead of the originals from back then, only the replicas made in 2009 still exist today. The actual border here was the Kreuzberg bank of the Spree. The gallery is located on the so-called Hinterland Wall, which closed off the border area to East Berlin.

A first wooden bridge was at the level of the former city wall, a few kilometers further downstream from the present bridge near the Spreeinsel. The Spree was blocked on both sides except for a narrow passage in the middle with walkable wooden walkways in order to be able to collect customs duties. At night the passage was closed with a thick trunk reinforced with iron nails, the so-called tree. In addition to the lower tree in the west of the city, there was the upper tree in the east. With the relocation of the city limits and the construction of the Berlin customs wall in 1723, a new wooden bridge with flaps for shipping traffic was built in place of the upper tree a little further east by royal order. Here the Stralauer Tor stood as the entrance to Berlin.

The control and check-in counters were in the Palace of Tears, manned by employees of the Ministry for State Security in the uniforms of the GDR border troops.
