The memorial to the Berlin Wall at the Marie-Elisabeth-Lüders-Haus at the home of the German Bundestag complements the installation "Parlament der Bäume" ("Parliament of Trees").
Ben Wagin created in 1990 the installation on the former border strip near the river Spree. The new installation consists of original pieces of the Wall marked with the number of victims killed at the Wall for each of the 28 years it divided the city. The underground level of the library shows the underground and surface route of the wall at the time. One of the first links to be re-established between East and West Berlin was the rebuilt Kronprinzenbrücke based on a design by architect Santiago Calatrava. The Wall Memorial is accessible from Schiffbauerdamm in Berlin-Mitte. Admission is free.
