The few segments of the Wall put up at Potsdamer Platz, as well as the Mauer Museum at Friedich Strasse, Bernauer Strasse and Checkpoint Charlie attract lots of visitors

, 

                                      and of course the Brandenburg Gate is a tourist magnet.

But most popular is the East Side Gallery near Warschauer Brücke. 

 

These are mostly artists' work after the Wall came down.

           Some of the real Berliner Mauer still stands at Bornholmer Strasse, 

                 that is where the Wall was first opened on 9 November 1989.

My Wall Memorial is a piece of the Berliner Mauer which our nephew Lars hammered out of it the day after the Wall fell. I mounted that bit of concrete with barbwire onto a collage of some of our Mauer pictures
