"but otherwise" in a sentence

"But otherwise" means"except for what has just been mentioned". In the sentence below, what does it mean?

Galicia, on the Atlantic coast of northern Spain, is the homeland of Generalissimo Francisco Franco, but is otherwise famous for being a place people try to leave.

[Suzy Hansen; NYT; 2012]

1. Galicia is famous for being the homeland of Generalísimo Francisco Franco and a place people try to leave.

2. Galicia is not famous for being the homeland of Generalísimo Francisco Franco, but famous for being a place people try to leave.

3. Galicia is famous for being the homeland of Generalísimo Francisco Franco, but is more famous for being a place people try to leave.

4. Galicia is famous for being a place people try to leave, but is more famous for being the homeland of Generalísimo Francisco Franco.

Is there another meaning but otherwise could have?

Simply put, when Galicia is introduced as the homeland of Generalissimo Francisco Franco, a reader would assume that this is Galicia's claim to fame as the General seems to precede his hometown. However, the author wants to point out that Galicia is in fact as, if not more, famous for its people wanting to leave.

An analogy would be, "India is where the number 0 was invented, but is otherwise famous for the founding of Gandhism." Here we are pointing out that the number 0 was invented in India, and it would be prudent if the article was one about India in a Mathematics magazine, but it is made clear that India is as or more well known for giving the world Gandhism.

It means for other reasons or in other ways. The passage says Galicia is famous for other reasons than being the home of Franco.

The phrase 'but otherwise' signals a clause that presents a diametrically opposite idea to what has just been said before.

I didn't like the ending, but otherwise it was a very good book. (The ending was not nice. However, the rest of the book was good).

He was slightly bruised but otherwise unhurt. (Except for minor bruises, he was not hurt).

Galicia ... is the homeland of Generalissimo Francisco Franco, but is otherwise famous for being a place people try to leave. (Galicia is historically significant for being Gen. Franco's homeland. However, there are other reasons why people want to leave the place. The first clause presents an apparently positive aspect of Galicia, while that following but otherwise presents a negative aspect. Notice that famous seems to have been used in a sense of irony here.)
