The Anne Frank House museum has launched an online virtual tour of the secret rooms in which the Frank family and other Jews lived. The tour shows the rooms, which have about 1 million visitors annually, in great detail. Teenager Anne Frank hid and wrote her diary in the secret annex of a building in Amsterdam during the Nazi occupation. Anne and the other eight residents of the secret rooms were arrested in August 1944 and sent to Nazi concentration camps. Only Anne's father, Otto Frank, survived.
