Schloss Ringberg, Heritage castle in Kreuth, Germany.

Schloss Ringberg is a castle complex of pale cream and light grey stone on a wooded slope of the Ringberg at about 906 metres, above the Tegernsee. A long multi-storey range with steep grey roofs, round and square towers and a ground-level arcade encloses a small courtyard; a square tower with a balcony rises from the centre, and a wing with a pyramidal roof projects to the right.

Duke Luitpold Emanuel in Bavaria decided in 1911 to build a castle on the Ringberg, where his family owned land. Construction began in 1912 and continued for over sixty years, financed by selling Possenhofen Castle and his Munich property. The duke died in 1973 with the castle unfinished; under a 1967 inheritance contract it passed to the Max Planck Society, which converted it into a conference centre opened in 1983.

The castle displays a mixture of different building styles, ranging from historical forms to Art Deco. Those passing by outside can recognize this artistic variety in the facade and roof shapes.

The castle is operated today by the Max Planck Society as a conference center and is not accessible to individual visitors. Those wishing to admire the exterior can catch glimpses of it from hiking trails in the surrounding area.

Friedrich Attenhuber was a Munich painter, not an architect, who designed everything at Ringberg from the architecture to the interior decoration and paintings. He took permanent residence in 1930 and in 1947 jumped to his death from the castle tower. His earlier Post-Impressionist works hang on the second floor, his later realistic paintings on the ground and first floors.
