The pedant in me wants to say that Berlin wasn't in West Germany. East Berlin was sort of in the DDR (the Allies refused to accept that though, legally speaking) and West Berlin was a specially administered area under the control of France, the USA and the UK. While in most senses and purposes it was part of West Germany, legally, it wasn't (it had to annually pass a law to accept all West German law changes, e.g.).

So if our question asker is a smarty bidarty, Berlin may NOT be one of the answers.
