There are an awful lot of mass grave sites to look at in the world.

It's no secret that there are linden trees nearby.

OK. I'm on a different track. Linden = connected to magic in folklore and legend. But, finding some Arthurian site is does not seem like I'm on the right track.

OK, we found it.

Ok. Where is it?

Gestapo HQ in Berlin :D

The Topography of Terror

Well, I guess Swanie beat me to the actual naming post so SHE has to find a new location. :evil:

Damn ;)
