The manor at Altmannsdorf was first mentioned in 1290. But it was only in 1973 that the 17th century manor house was restored and a modern hotel building erected on the site of the former servant's wing. After being successfully converted and refurbished in 1993/94, the hotel rapidly became the leading seminar and conference hotel in Vienna under the management Bernd Th. Schmid. Its interesting architecture so impressed an international jury that the WIENER GARTENHOTEL ALTMANNSDORF was awarded the national prize for tourism and architecture.
