Checkpoint Charlie was the most famous border crossing between East and West Berlin during the Cold War, and today it stands as a powerful symbol of Berlin’s divided past. Located on Friedrichstraße, this historic site features a replica of the original guardhouse, photo displays, and nearby exhibitions documenting escape attempts and life behind the Berlin Wall. While the outdoor site is free to visit 24/7, the adjacent Wall Museum at Checkpoint Charlie offers deeper insight into the history, with exhibits, documents, and artifacts from the era. It’s a must-visit spot for history lovers exploring central Berlin.
