Is it a complete anagram using all of the letters or just "has two towns/ cities" in the phrase? Birmingham and Derby in UK both have cathedrals, but some letters are left over, so it is more than likely to be incorrect.
Yes, apart from "Birmingham" & "Derby" I also got "Bath" out of it; and possible endings might be "-bridge" or "-minster", but nothing seems to work using all those letters, so I, too, rather think there's a mistake somewhere!
"Abbey" would also be possible , but after looking at a complete list of famous cathedrals in Britain & even the world in general, I'm sure there's an error here! Sorry!
