View of the tiergarten from the top of the Reichstag building in berlin.
Tiergarten (German for Zoo) is the name of both a large park in the centre of Berlin and a locality within the borough of Mitte. Before German reunification, it was a part of West Berlin. Until Berlin's 2001 administrative reform, Tiergarten was also the name of a borough, consisting of the current locality of Tiergarten (formerly called Tiergarten-Süd) plus Hansaviertel and Moabit. A new system of road and rail tunnels runs under the park towards Berlin's Central Station in nearby Moabit.
