Reichstag and Foster's Glass Cupola

In the last 100 years, this massive neo-Renaissance building has been set on fire, bombed, wrapped in paper by artist Christo, and renovated by Lord Norman Foster. It is now the seat of the German Parliament. Climb the mesmerizing glass cupola and enjoy a breathtaking 360-degree-view of the city, then look down to watch the parliamentary proceedings taking place. Reservations for Käfer Dachgarten, the rooftop restaurant, are required. The plenary hall can be visited on guided tours only. Käfer Cupola: Daily 8am–midnight by appointment only. Register on website; it is highly recommended that you do so at least three days in advance, more during peak times. Audio tours available. Free.
