Tiergarten (German for Animal Garden) is a locality within the borough of Mitte, in central Berlin (Germany). Notable for the great and homonymous urban park, 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 Bezirk 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 main station in nearby Moabit.
