I have put Ellingen rather than Erlangen, chiefly because I came across it first, though it appears to be somewhat smaller. It fits the puzzle and is also in Bavaria, and features in both my World Atlas and my Europe Motoring Atlas, so I'm hoping they will allow either. Not everyone has a Collins English Dictionary, and I can't help wondering whether it would have featured in the Sunday Express Crossword Dictionary (a whole £28.01 cheaper than the Collins), which I don't have either!
