Tristan Chamber: Terra-Verde - MMural - Picture of Runkelstein Castle, Bolzano [+]
hm... this morning found a postcard hidden in the back of my desk "Tristan cuts out the tongue of the dragon", must be from my days in Switzerland, when we went to visit the South Tyrol (which was Austria until 1919)
For German readers there is a pdf Der Bilderzyklus von Tristan und Isolde im Sommerhaus, showing all pictures of the castle.
