Stein Castle is the most important cave castle in Germany. The origins of the upper house are not totally clear. It may have stemmed from a fortification dating to the Roman or Celtic period. Stein was first recorded in 1135. The romantic figure of the legendary robber knight, Hainz von Stein dem Wilden, is closely associated with the castle. He is supposed to have lived in the castle in the early 13th century and was written about for the first time by Lorenz Huebner in 1783.
The castle itself was in the possession of the Toerring family from the 13th century to 1633 . Albert von Toerring-Stein was the Bishop of Regensburg from 1613 to 1649. Adam Lorenz von Toerring-Stein held the same office from 1663 to 1666.
Count Carl Fugger von Kirchberg bought the property from the Toerrings in 1633. Later it passed by marriage to the lords of Lösch.
In 1818 a 2nd class patrimonial court was established in the old Hofmark in the wake of reforms in Bavaria. In 1845 Amélie de Beauharnais, widow of the emperor of Brazil, bought Stein Castle for herself and her daughter. In 1848 she ceded the Stein Court to the state as compensation.
In 1890 Stein Castle went to Count Joseph zu Arco-Zinneberg. In 1928 the Arco-Zinneberg had to cut down the great St. George's Forest in order to sell the wood to get out of debt. Despite that they had to sell up, the forest was possessed by the state and was immediately reforested.
Upper house, rock castle and lower house are today the property of the newly built Stein Castle Brewery (Schlossbrauerei Stein), founded in 1907, which has been in the ownership of the Wiskott family since 1934. The lower house in Stein has housed a private boarding school since 1948, the Schule Schloss Stein.
References:The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
