The iconic Olympiastadion, originally constructed for the 1936 Olympic Games in Berlin, underwent a complete renovation in time for the 2006 FIFA World Cup. Now equipped with a sleek oval roof, VIP boxes, and advanced sound, lighting, and projection systems, it is worth a visit even on non-event days. Visitors can explore the stadium on their own (multimedia guide €2) or join a guided tour for access to the locker rooms, warm-up areas, and VIP areas. The Hertha BSC Tour must be pre-booked online.
