Cities with two names?

Which cities have two or more official names in different languages? I m not talking about translations into other languages (f.ex. London is "Londres" in Spanish) but about official names, for example Dublin is also Baile Athá Cliath, Brussels is Brussel in Flamish, Bruxelles in French and Brüssel in German, the three of them official languages in Belgium. In Spain there are several, one of them is Bilbao, which is called Bilbo in Basque. Do you know any other case?>
