Leopoldskron Palace in Salzburg, Austria (http://www.schloss-leopoldskron.com) was built in the 18. century. In the past 70 years, it was used for congresses and was only open to those participating in seminars held there. A businessman from Munich has turned the Rococo castle into a hotel. Historical elements have been kept and lovingly restored. The hotel opened its doors in February 2014.
