The Tiergarten (formal German name: Großer Tiergarten) is Berlin’s most popular inner-city park, located completely in the district of the same name. The park is 210 hectares (520 acres) in size and is among the largest urban gardens of Germany. Only the Tempelhofer Park (previously Berlin's Tempelhof airport) and Munich's Englischer Garten are larger.
The beginnings of the Tiergarten can be traced back to 1527. It was founded as a hunting area for the Elector of Brandenburg, and was situated to the west of the Cölln city wall, which was the sister town of Old Berlin. It also sat in the same vicinity as the City Palace (Stadtschloss). In 1530 the expansion began; acres of land were purchased and the garden began to expand towards the north and west. The total area extended beyond the current Tiergarten, and the forests were perfect for hunting deer and other wild animals. The Elector of Brandenburg had wild animals placed within the Tiergarten, which was fenced off from the outside to prevent the creatures from escaping, and was the main hunting ground for the electors of Brandenburg. This hobby, however, began to fade away as the city of Berlin began to expand and the hunting area shrank to accommodate the growth.
Frederick Wilhelm I (1688 — 1740), Elector of Brandenburg (1713 — 1740), feeling the need to bring change to his private hunting grounds, built many structures that are still visible today. As the King was expanding Unter den Linden, a roadway that connected the City Palace and the Tiergarten, he had a swathe of forest removed in order to connect his castle to the newly built Charlottenburg Palace. Der Große Stern, the central square of the Tiergarten, and Kurfürstenplatz, the electoral plaza, were added, with seven and eight boulevards respectively. This is seen as the beginning of a transformation in the Tiergarten, a movement from the king’s personal hunting territory to a forest park designed for the people.
