At one time the royal stables, this 16th-century building now houses the Verkehrsmuseum (Transportation Museum), a collection of historic conveyances, including vintage automobiles and engines. The former stable exercise yard, behind the Johanneum and enclosed by elegant Renaissance arcades, was used during the 16th century as an open-air festival ground. A ramp leading up from the courtyard made it possible for royalty to reach the upper story to view the jousting below without having to dismount. More popular even than jousting in those days was Ringelstechen, a risky pursuit in which riders at full gallop had to catch small rings on their lances. Horses and riders often came to grief in the narrow confines of the stable yard.
On the outside wall of the Johanneum (behind the building on the Auguststrasse) is a remarkable example of porcelain art: a 336-foot-long Meissen tile mural of a royal procession. More than 100 members of the royal Saxon house of Wettin,
half of them on horseback, are represented on the giant mosaic, known as the "Procession of Princes," which is made of 25,000 porcelain tiles, painted in 1904–07 after a design by Wilhelm Walther. The representations are in chronological order: at 1694, Augustus the Strong's horse is trampling a rose, the symbol of Martin Luther and the Protestant Reformation. The Johanneum is reached by steps leading down from the Brühlsche Terrasse.
