The Anne Frank House is a museum made in memory of the suffering of Jews in World War II in the Netherlands. The Frank family spent much of the war in the annex of the house where her father moved his spice business in 1940. Since it was customary in the Netherlands not to cover the windows with curtains, the family could only hide in the backroom in absolute silence, and at night in absolute darkness, about which the girl Anne kept a diary, which is on display in the museum. Despite all the precautions, the Nazis discovered them and took them to concentration camps in 1944, and only Anne's father Otto survived.
