Engleithen Castle

Engleithen Castle (also known as Villa Rothenstein) is located in the municipality of Bad Ischl in the Gmunden district of Upper Austria.

The castle was built in 1896 by the Viennese financier Rothenstein. Oskar Blumenthal lived in the castle during the summer months and wrote the operetta Im weißen Rössl here. Max Reinhard was a frequent guest here in the 1930s, as were Hugo von Hofmannsthal, Jakob Wassermann, and Clemens von Franckenstein.

In 1917, the castle came into the possession of Baron Edgar von Spiegel († 1932) and his wife Lucy, née Goldschmidt-Rothschild. Baron von Spiegel established a folklore museum in the house. This was donated to the Linz Castle Museum in 1967.

In 1957, Baron Spiegel's widow sold the castle to a family community. In 1961, the headquarters of the PKS Academy (= Pythagoras-Kepler-System) for Biotechnology was established here under the direction of Walter Schauberger († 1994).
