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. Its interesting architecture so impressed an international jury that the hotel was awarded the national prize for tourism and architeture. The hotel was opened in 2005. Designed by the architects Michael Schluder and veronika Vogelbauer, this house represents cotemporary hotel design.
