EllenS - This is indeed in Germany, and you were very astute to see the non-standard Bavarian flags; the checkered blue-white pattern is far more prevalent.

Carol - While Neuschwanstein is in Bavaria, it is a very long way from this picture's location and it was built by crazy King Ludwig. This location is much older. European Royal families intermarry quite bit and this location has lots of roots to royalty in such countries as Russia, Belgium and even Great Britain.
