context_page_description: A submarine pen is a type of submarine base that acts as a bunker to protect submarines from air attack. The term is generally applied to submarine bases constructed during World War II, particularly in Germany and its occupied countries, which were also known as U-boat pens.
context_section_description: Only 6 kilometres (3.7 mi) separate La Rochelle and La Pallice so they are usually considered as one port. An unnamed bunker was built at La Pallice (Base sous-marine de La Rochelle); it was started in April 1941. Similar building techniques to those used in St. Nazaire were employed. Due to the relative ease of construction, the main structure was ready for its first U-boats six months later. A bunkered lock was begun in June 1942. It was completed in March 1944. Scenes for the 1981 films Das Boot and Raiders of the Lost Ark were shot in La Pallice.
