    The Hotel Imperial is a luxury hotel located on the Kärntner Ring. Built in 1863 as the city palace of the Duke and Duchess of Wurttemberg, its original name was Palais Wuttemberg. However, the Duke and the Duchess lived in it for only five years before selling it. It was converted into a hotel in 1873. Now taller by two stories added in 1928, it is still a first-class hotel on the Ringstrasse.
