The Imperial War Museum has five branches, three in London, and the main one is the dome on London's LEMBETH Road. The other two are: Duxford, 9 miles south of Cambridge, the largest space museum in Europe, with nearly 200 old-fashioned aircraft models, and HMS Belfast, a cruiser docked across the Tower of London and along the Thames River, which restored the look of the cruiser. The Imperial War Museum is open to the public free of charge, but it sells all kinds of souvenirs, introductions and books about the museum. Many of them are very meaningful and worth recommending. The collection includes items ranging from aircraft, armored combat vehicles, naval vessels to uniforms, badges, personal equipment, medals and decorations. There is also a big lawn outside the library, where you can take dry food with you. Here you can have a lunch and feed pigeons casually.
