Reichstag

A political Phoenix, literally risen from the ashes
Word to the wise: As this is a working parliament building, guided tours must be booked in advance.

Home of the modern German parliament (the 'Bundestag') since 1999, the 'Reichstag' was actually the name of the old parliament building, badly-damaged by fire in 1933, and derelict for 50 years until rebuilt by Sir Norman Foster – between 1992 and 1999 – into its current magnificent state.
Contrary to popular belief, Hitler never physically held office here as German Chancellor, despite his grand plans to rebuild it as the flagship icon of his 'new Berlin'. It's still a popular tourist destination, nonetheless, not least because of the magnificent glass dome that visitors can walk around as part of a free guided tour or by registering for free in advance online.

Situated on the northeastern edge of the Tiergarten, across the road from the Brandenburg Gate, this area is rich in German history and worth a day on its own.
