Is there a specific region of Italy that is known for anchovy pizza? Can you get that in all of Italy or is that specific to a region? Can you actually get a buffalo mozzarella anchovy pizza? Im trying to flesh out the specifics of my culinary bucket list. I’m assuming Italians actually do anchovies on pizza. I know they have nothing but disdain for those who put pineapple on pizza. 
Napoli. Prior to the blessing of Pizza Margharita as the official pizza of Napoli, the locals equally enjoyed pizza with tomato sauce and anchovies.  So much so, that this pizza is still known as Pizza Napoli. So if you're looking for a traditional, "canonical" anchovy pizza, that's the place to go.
