The name together with its monumental size make most people associate Germany's neoclassical parliamentary building with the Nazis, but they have little history here. After hosting parliamentary sessions since 1894, it was set on fire just one month after Hitler was appointed chancellor in January 1933. It was a conference centre in the years during which it abutted the Wall, while later artist Christo famously wrapped it in cloth. It was used as parliament again after a reunited German government returned to Berlin in 1999. Renovated by Sir Norman Foster, this building is perhaps the most public federal building in the world through its glass dome. On the rooftop, photographs documenting the building's history circle the rim above the parliament chamber. Two ramps spiral up the side of the dome, an engineering feat even more fascinating than the panoramic view from the top. It's best to book an entry time to the dome or for the 90-minute guided tour of the building in advance online; otherwise queue up for remaining places at the visitor centre just across the road. Photo ID is required.
