Thank you. This might be some remains of the long during Califat in Al-Andalus. If you refere to the original story, it get's sens. However, Barcelona never was realy part of it.
There is at least one exception to this conventional representaion. Every city map of Barcelona is drawn the mediterranean at the bottom or West on Top. If you know others tell me.
Beethoven is just german as much as Germany didn't realy exist by this time. But Mozart parents where from Augsburg, and he was born in Salzburg on a professional voyage of his parents. Nevertheless he spent most of his life in Austria.
