Had a chance to do get inside the Villa last week, and do an in-depth tour.
When time permits, will post some photos . . . for now, here's a few "thumbnails" - showing the outside of the villa, the balcony, the grand staircase, the large entertaining room [where Heydrich practiced his fencing skills], the swimming pool, the front gate, the guard-house [which was originally a weinstube], and the lovely little guard-dog's that keep the place safe at night.
Another curious tidbit of information came out of the visit . . . it seems the older son of Heydrich was buried on the premises - and I have snapshot of the [reputed] location. A video I made - of an interview with a past servant - goes along with the explanation . . . and hopefully, I can figure out how to include this in the future post.
