The city sustained heavy damage during World War II. Many Jews were killed during the German occupation. Additionally, the Atlantic Wall was built through the city, causing a large quarter to be torn down by the Nazi occupants. On 3 March 1945, the Royal Air Force mistakenly bombed the Bezuidenhout quarter. The target was an installation of V-2 rockets in the nearby Haagse Bos park, but because of navigational errors, the bombs fell on a heavily populated and historic part of the city. The bombardment wreaked widespread destruction in the area and caused 511 fatalities.
