Opening in April 1828, London Zoo was originally intended to be a collection of animals for scientific study. The animals of the Tower of London menagerie transferred into the collection in 1831. The zoo was then opened up to the public in 1847 and has been growing and striving ever since. It is now home to 698 species of animals and is one of the largest collections in the United Kingdom. Due to it being located in Regents Park, it is sometimes called Regents Zoo. The Zoological Society of London manages the zoo and a larger site, ZSL Whipsnade Zoo, which is in Bedfordshire where larger animals are kept.
