Planning to make the 11am free walking tour which left from the Brandenburg gate we walked past Alexanderplatz, past Museum Island & down Unter de Linden and despite arriving ten minutes late we managed to tag onto the back of a tour taken by an Aussie guy. The first stop was the Holocaust Memorial which is made up of over 2000 grey blocks set in rows on an undulating open space so that as you walk through the columns are different heights. It's an interesting memorial but good that it attracts people to think about why it is there so we hopefully learn from the past. We continued towards Check point Charlie stopping along the way to listen to antidotes from German history- both good and bad. Along from here we passed a section of the Berlin wall still standing which backs onto the former headquarters of the SS but now houses the Topography of Terror exhibition. Looping back around the tour finished back at the Brandenburg gate so we stopped for a traditional Berlin Currywurst (pretty much a chopped up hotdog with lots of sauce & some curry powder on top) before heading off towards the Reichstag- the home of the German government with its modern glass dome set on top of a typical imposing square classical building. Now on the edge of the Tier garden we zig zagged through this enormous wooded park past the Angel of victory statue which sit in the middle of a large roundabout & is decorated with cannons captured from the French. Unfortunately we then passed the nude sun baking section of the park before continuing to a beer garden at the edge of the park for a well earned drink even if the wasps tried to share! Walking along the canal & past the back of the zoo we finally came to the bottom of the park at Zoogarten station where we wanted to see the bombed memorial church but unfortunately it was totally covered in scaffolding due to restoration work. A few stops on the train & we were back at Alexanderplatz where we had cheap (€4.50) stir fry noodles which gave a much needed vegetable fix. After another massive day of 25,000 steps (17.5kms) we finally arrived back at the hotel for a much needed rest.
