1 Para. 12 DMSG). For the Lower Austrian state garden show of 2008, the park was revitalized based on the design principles of a 19th-century landscape garden. In 2007, the 'Wolkenturm' ('tower of clouds'), an open-air stage with 1,700 seats and 300 grass seats, was constructed in the park east of Schloss Grafenegg. The open-air pavilion was designed by the next ENTERprise (Marie-Therese Harnoncourt, Ernst J. Fuchs) and the landscape architects Land insicht. The sculptural building takes up the element of the amphitheater as a garden inventory of the type of baroque garden and quotes formal elements of the old stock in the park. Gutshofsiedlung On the northern edge of the park is the so called Gutshofsiedlung, a group of houses consisting of a porter's house, a mighty granary, two one-storey commercial wings, a mill, several residential buildings, a manager's house and a large farm. In 2008, the ensemble was expanded to include the Grafenegg auditorium, which was designed by the architects Schröder Schulte-ladbeck and Dieter Irresberger and sound-designed by the Munich acoustician Karlheinz Müller. This hall can serve for up to 1300 listeners a concert hall. The shape of the open, irregular, polyhedron glass building blends in with the old building. Schloss Grafenegg today Most of the stately rooms in Schloss Grafenegg can be visited. Since 1971, various events such as exhibitions, concerts, conferences have taken place at the castle. Each year there is a Christmas market (the 'Grafenegger Advent'). Between 1984 and 1987, the castle was the setting for an Lower Austrian state exhibition on the age of emperor Franz Joseph I of Austria. The initiator and driver of the cultural activities on the castle grounds was its managing director Gerhard Großberger. He made Schloss Grafenegg a fixed point in Austria's cultural landscape. In addition, there are on the castle grounds a riding school, a hotel, a restaurant and a vinotheque. In the park, there are the open-air stage 'Wolkenturm' with 1750 seats, completed in 2007, and the Auditorium Grafenegg concert hall, which serves as a venue and alternative location for the open air stage. Both are used for the Grafenegg Festival under artistic direction of Rudolf Buchbinder, which takes place every year (since 2007). The park and gardens are also used Lower Austrian State Horticultural Show. Further, the castle has been used in various (German spoken) movies and series. References This page is based on this page
