This memorial pays tribute to what is perhaps a lesser known tragedy from Nazi Germany. During the 1930s and 1940s, 96 members of the German parliament were prosecuted and eventually killed for disloyalty to the socialist regime. The memorial sits in front of the Reichstag, where the German Parliament meets today.
Further west of Checkpoint Charlie, sits an imposing watchtower known in German as the Rundblickbeobachtungsturm. The tower is the last the last of its kind still standing, the others being later replaced with bigger versions. This particular tower dates back to the 1960s and was declared a historic monument in 2001.
Situated a five-minute walk away from the checkpoint on Niederkirchnerstraße, right behind Prussian buildings and the Martin-Gropius-Bau, is a 200m (656 feet)- long original piece of the so-called Grenzmauer 75, the fourth generation of the Berlin Wall.
