In Berlin you can visit significant buildings of Germany's turbulent history in museums and original sites. The German capital was the center of many historical events, such as the division of the country and the construction of the Berlin Wall. You can learn about these events at the East Side Gallery. Here you can see the world-famous remains of the wall, painted by artists. But you can also experience the history of the city while sightseeing at Checkpoint Charlie or at the Berlin Wall Memorial. If you are interested in the founding of the city, a trip to the Nikolai Quarter near Berlin's Alexanderplatz is worthwhile. Here you will find the Nikolai Church, the oldest surviving building in the city.
