Ringberg Castle on Tegernsee is the final example of the long-standing building tradition of the Wittelsbach dynasty. Duke Luitpold had this mighty complex built over a period of six decades, from 1913 to his death in 1973, taking as much interest in its progress as his uncle King Ludwig II had during the construction of his "fairy tale castles." As a work of art, Ringberg is unequalled in Europe. It impressively reflects all the changes in art during the periods covering late Historicism, Art Nouveau, Art Deco, regional styles, Neo-Classicism, Modernism and National-Socialist-Classicism. The architecture and furnishings were the work of a single individual - the Munich painter Friedrich Attenhuber, Luitpold's house-artist. Duke Luitpold bequeathed Ringberg Palace to the Max-Planck-Gesellschaft, which today uses the premises for academic conventions.
