I know, but as I said it is especially historic and mentioned in tourist guides, such as here:

I also added tourism=attraction to Jomfru Ane Gade, since I know many Norwegians travel to Aalborg just to got there.

But you are right; wikipedia page does not mean it is automatically a tourist attraction.
