The Anne Frank House is a writer's house and biographical museum dedicated to Jewish wartime diarist Anne Frank. The building is located on a canal called the Prinsengracht, close to the Westerkerk, in central Amsterdam in the Netherlands. During World War II, when the Netherlands was occupied by Germany, Anne Frank hid from Nazi persecution with her family and four other people in hidden rooms, in the rear building, of the 17th-century canal house, later known as the Secret Annex.
