tagging on to T_S's comment below, but putting it here so you'll see it... (for reference, I was in Spain with Brian last year when these things were sighted)

Yes, it was the Jamonasterio and it is indeed a monastery where they specialize in a particular kind of Jamon. They hold a TWO WEEK festival of Jamon every year. The mind boggles. People apparently make Jamon-tasting journeys, much as people do wine-tasting here in CA. And there's a Palacio de Jamon in Madrid as well... We didn't actually get inside, so I can't guarantee it wasn't made of ham, though....
