At the story of Berlin, we took a tour down to a bunker which served as a nuclear shelter during the Cold War. According to the tour guide, the bunker would function for only two weeks after a nuclear strike and provide people with the most basic needs. Each of the 3000 beds was only 170cm long and they all had to share 2 women's toilets and two men's toilets. They could only eat one can of food per day. It was very interesting to see all the old stuff they had from the 1970's and I'm sure everyone had a good experience as well. We also went through the history of Berlin, which was a self guided tour in 24 stages.
After that, we went to Madame Tussauds, where we got to 'meet' our favourite people in the world. People such as Mezut Özil, Barack Obama, Michelle Obama and Justin Bieber (not them personally) were made out of wax. I had so much fun there because every celebrity I saw looked so real (I kind of fangirled a little bit when I saw One Direction) and It was simply awesome.
After that, we spent a little bit of time in the Mall of Berlin before we headed back home.
