Berlin’s most iconic building, the Fernsehturm on Alexanderplatz, was built by the GDR (East Germany) in the 1960s with the double purpose of transmitting television signals and demonstrating the strength and efficiency of the socialist system. Its rocket-like structure showed the East German government’s enthusiasm for technology and space, and the sphere was designed to resemble the Soviet Sputnik satellite. Standing 368m (1027ft) tall, it's the tallest building in Germany, and with a 40-second elevator ride, you can reach the observation deck and Bar 203, which serves drinks and snacks. Restaurant Sphere is on the next floor at 207m (680ft), serving traditional Berlin cuisine and international dishes. The restaurant makes a 360-degree rotation every hour, guaranteeing a spectacular sightseeing tour at every table, but you’ll need to reserve in advance. Arrive early to avoid lines. Daily 9am–midnight (Nov–Feb from 10am). €13/8.50.
