Okay - the history! The House at the Two Golden Bears

I feel shamed into actually finding out more about The House at the Two Golden Bears (in my defence I am up to my ears in Victorian Gothica right now, though I suppose that's a poor excuse.) so here is an article. The house is described as "Baroque" but like so many houses here, I'd guess it's originally much earlier. Our house is 14th century but makes a very good job of looking 1930s modernist - someone's idea of stylish no doubt. Anyway, here is the whole story - okay, a very little bit of it - of the possible link with alchemy. I should add that I don't find the explanation of the bears at all convincing, but that's another conversation I suppose.
