A 1986 grassroots effort to uncover the remains of the Nazi offices. Sites of Hurtful Memory
 

A 1986 grassroots citizens effort to uncover the remains of the Nazi offices headquartered at the Prinz-Albrecht site. This symbolic archaeological act led to professional excavation at the site, and to the conservation of the Gestapo headquarters cellars subsequently uncovered. The following year, in conjunction with Berlin's 750th anniversary, a didactic walkway was developed and the Topography of Terror exhibition was installed in an excavated cellar to aid visitors in interpreting the site.
