The great city of Middelfart ;) https://en.m.wikipedia.org/wiki/Middelfart

In Denmark we have the digraph “aa” that is the same as “å”. Since “å” is the last letter in the Danish alphabet, “aa” must be sorted likewise. Hence the ordering Aalborg -> Allerup -> Middelfart is incorrect and the correct ordering is Allerup -> Middelfart -> Aalborg.

The exception is if two a’s are pronounced as separate vowels e.g. due to compounding words: “ekstra” + “arbejde” gives “ekstraarbejde” but here it is not pronounced as “å” so ekstraarbejde -> ekstrabetaling is correct ordering as well
