Although very little of the Wall remains as of now, three long sections are still standing: an 80-metre-long stretch at the Topography of Terror, site of the former Gestapo headquarters; a longer section of the second wall along the Spree River near the Oberbaumbrücke; and a third section that was partly reconstructed at Bernauer Straße, and turned into a memorial in the year 1999. https://en.wikipedia.org/wiki/Berlin_Wall

Many people created graffiti art on the walls to express their feelings. However, much of the artwork was not claimed by artists and still remains anonymous. The Berlin Wall became symbolic of the pain and suffering during that era, and acted as a canvas for people to convey their thoughts. A lot of books were published on the stories revolving around the Berlin Wall such as "A Night Divided" by Jennifer Nielsen and Petere Schneider's "The Wall Jumper: A Berlin Story".
