The representation of the numerous remnants and traces of the Berlin Wall complements that of those Wall segments and watchtowers listed and protected as post-WWII heritage. The documentation of the border and landscape of memory from remnants of the Wall strip was compiled between 2001 and 2003 by the Department of Conservation of the Brandenburg University of Technology Cottbus, commissioned by the Berlin Senate Department for Urban Development and the State Conservation Agency of Berlin. However, by far the greatest part of the border fortifications universally known as the "Berlin Wall", erected by the GDR all around West Berlin from 13th August 1961 onwards, were dismantled in 1990 and 1991.
In addition to the present textual documentation, the results of a detailed survey by the Department of Architectural Conservation, BTU
Cottbus were also documented in an interactive map
at the time.
