Ooo, I love this thread!
Here are a few pictures (which I did not take) of KKG headquarters.
A few years ago I had an opportunity to go but didn't, and I really regret it. I hear it's beautiful.

Large crest inside

One of the Founder's keys! I believe it is the only one that is known to still exist.
I look forward to seeing some more pictures from my sisters - I'm pretty sure LucyKKG has some!
