The Saxon Palace (Polish: Pałac Saski) was one of the most distinctive buildings in prewar Warsaw, Poland. The Saxon Palace had originally been a private palace of the Morsztyn family, then had been purchased and enlarged by the first of Poland's two Saxon kings. It was in this building that the German Enigma machine cipher was first broken in December 1932 and then read for several years. The Biuro Szyfrów (Polish for "Cipher Bureau") was the Polish interwar agency charged with both cryptography (the use of ciphers and codes) and cryptanalysis (the "breaking" of ciphers and codes). During World War II, the Saxon Palace was destroyed (it was blown up by the Germans after the collapse of the Warsaw Uprising in 1944.
