Prince Johann Adam Andreas I of Liechtenstein loved Italian art and had this garden palace built in 1700 as a Roman-style city villa. This architectural work of art opened its doors in 1807 and continues to exhibit the prince’s art collection today. To view the masterpieces, which range from the Early Renaissance to the High Baroque period, you’ll need to take a guided tour. The sculptures in the garden, however, are accessible to the public. The grounds and the Stadtpalais are both magnificent (Bankgasse 9).
