Most visitors come to Berlin demanding to see where the infamous Berlin Wall once stood. But in the fervor to dismantle a hated symbol of Russian oppression, much of the Wall no longer exists. Now a GPS multi media guide makes it easier for curious tourists to hit the places where the wall once stood. It kicks off the first of May, and visitors can hear the voices of wall history, look at photographs and read about the history at the East Side Gallery, where a remnant of the Wall remains, and the Topographie of Terror, which was also the site where many political prisoners were tortured under the Nazis. In this segment, we follow a Berlin visitor touring the history of the wall.
