This museum, at a former blockhouse used for the manufacture and launch of V1 flyer not bombs and V2 rocket bombs, is well worth a visit, no matter what your level of knowledge is. There’s no “sanitisation” about the destruction or either of the world wars. The visit, with a discount for those aged over 60, coats £15 including a film in the planetarium. There are also other documentaries with original film, about concentration camps and other aspects of both wars. My husband and I were there for about 5 hours.
