I’m not sure actually, because the river has different names in different languages. In Finnish it is Tonava, Danube might be what the English use. The Maps in iPhone say Duna, so that is what I used this time 😁

You are right about Danube, it is the English name. I have heard people calling it Tonava, but never for Duna (without the v in the end). Well I have learned something new today about a river I tought I know all about. Say hello to it for me, it has been a long time since our paths have crossed each other.
