I grew up in Denmark's 2nd largest city, Århus.
But strangely, Denmark no longer has a city by that name.
Århus was originally named Aros from 700-1406, when the city name changed to Aarhus. But in 1948 Denmark had a spelling reform where the character Å was introduced to represent Aa, and Aarhus became Århus.
However, because of international tourism and events, the city council decided to revert to the old name Aarhus in 2010, making it easier to spell internationally without the Å.
