Originally the kitchen and herb garden of the Royal Palace, the Berlin-Dahlem Botanical Garden (Botanischer Garten Berlin-Dahlem) was built in 1679 on the instructions of the Grand Elector.
Covering 126 acres, it is one of the world's largest botanical gardens, home to more than 20,000 species of plants that represent the flora of not only Europe but also tropical and subtropical environments in the Great Tropical House.
There are also gardens of medicinal plants and a large pond forming the centerpiece of the biotope for marine and marsh plants.
