Gnomey your last pic is looking off the Marien bridge that I mentioned.
the grotto is actually in his other place of residing or so it was said, Linderhof which is actually somewhat around the corner of the road in the Graswang valley. also in the Graswang valley a ways is his fathers Jagdhaus. Ludwig was not mad at all unless you call someone that spent the peoples monies in hordes for these lavish places. Excentric, nah, gay, yes he was but had an eye for oppulance.
If you ever take a visit make sure it is quite lenghty as Adler can confess, your eyes will pop out at all the richness of the German Baroque period outside and within the many Schloss and Catholic churches. the Luftmaleri on the outside of many, many of the upper Bayerische towns, Oberammergau and Garmsich of note. If I get the chance I am coming back..........
