I have driven past this little gemstone a hundred times, and it took me over a year to actually visit. It’s a bit hard to describe, but I’d say it’s a self-sustaining little village, where they have their own livestock and grow their own food. There are 3 restaurants on site, as well as a hotel, grocery store, butcher, bakery, and more. It’s super cute!
It was a nice little place! You can visit their website here: http://www.domaene-mechtildshausen.de/
Beware, though, it’s in German!
