The Berlin Aquarium is located next to the Zoological Garden and thus in the Berlin-Tiergarten district. Its history goes back to 1913. It was then quickly growing into one of the world's largest aquariums. It was almost completely destroyed in the Second World War. It is only fully functional again after extensive reconstruction, renovations and extensions. Today it is home to freshwater and marine animals as well as reptiles, amphibians and insects. Due to the dense spatial location, visitors can buy single tickets or opt for a combination ticket that includes a visit to the zoo. Both buildings are under monument protection and are run as a not-for-profit and listed stock corporation.
