The Natural History Museum at Tring, located in the grounds of the former Rothschild family home of Tring Park, was originally the private museum of Lionel Walter, 2nd Baron Rothschild.
The building was constructed in 1889 to house Rothchild's collection of mounted specimens, and first opened to the public in 1892. The Rothschild family gave the museum and its contents to the nation in 1937, and it is now managed by the Natural History Museum, London. It was known as the Walter Rothschild Zoological Museum until 2007.
