Congratulations!
As far as the global thing, I totally agree with you. We have too many US/Canada only categories. I voted against the German-American category, because I felt it should be much wider - at least Western Hemisphere if not anything outside Europe.
I would object to a category that purposefully excluded US and/or Canada without a good reason. I believe your category has one! (I'm assuming that they're excluded - I'm not aware of any Baroque buildings that old on this side of the pond)
I hope to one day be able to post in your category, but it will be a while. The only building near me that is that old (at least as far as I know) is a pyramid. I'm sure it's not Baroque. Besides it's also underwater and I would need to learn to Scuba (or rent one of those underwater subs) to get a picture of it!
