East Berlin was the capital of East Germany, officially known as the German Democratic Republic (GDR), from 1949 until the reunification of Germany in 1990. It was separated from West Berlin by the famous Berlin Wall, which was built in 1961 to prevent East Germans from fleeing to the West. The city was characterized by its socialist architecture, state-run economy, and a unique cultural scene that included theater, music, and art. After the fall of the Berlin Wall in 1989, East Berlin underwent significant changes. The reunification process brought new opportunities for development and investment, transforming the area into a vibrant part of the unified city. Today, East Berlin is known for its rich history, diverse neighborhoods, and landmarks like Alexanderplatz
