Ann Frank was hidden
During World War II, Anne Frank hid from Nazi persecution with her family and four other people in hidden rooms at the rear of the 17th-century canal house, known as the Secret Annex (Dutch: Achterhuis). She did not survive the war but her wartime diary was published in 1947. Ten years later the Anne Frank Foundation was established to protect the property from developers who wanted to demolish the block. The museum opened on 3 May 1960. It preserves the hiding place, has a permanent exhibition on the life and times of Anne Frank, and has an exhibition space about all forms of persecution and discrimination. In 2013 and 2014, the museum had 1.2 million visitors and was the 3rd most visited museum in the Netherlands, after the Rijksmuseum and Van Gogh Museum.
