Austria and France signed an armistice in Zámek Slavkov (Slavkov Castle) on Dec 6th, 1805. At that time, the place and the mansion were known by the name Austerlitz. Taking a guided tour, I had the chance to see not only the interior of the Baroque building but also the room where the armistice was signed.
