The oldest part of Berlin grew up at the area called the Nikolaiviertel. It is situated down at the River Spree next to the Rotes Rathaus – the red city hall. The area is home to the oldest church in Berlin. The old town had been demolished over time and the old building had been torn down.
Berlin had its official 750 anniversary in 1987 and the communist leadership of East Berlin decided they would remodel the area around Nikolaiviertel so it would look a bit like an ancient part of the city. I think it is fair to say they failed in this attempt – the building doesn’t look like an old town.
The area may not be that interesting from an architectonical point of view but the area is fairly quiet with limited traffic and a lot of different small restaurants and bars you can visit for a quite dinner or a drink if you are exploring the area.
