Built in 1385 and known as the Neuveste, the first tenant at the Residenz Palace was Duke Stephan III, who reigned from 1375 to 1392. The palace was expanded under the tenure of Duke Wilhelm IV from 1508 until 1550. Part of the expansion included the construction of the Antiquarium, a magnificent Renaissance hall. Every subsequent monarch that moved into the palace, it seems, added yet another room or two to the residence; from ballrooms and chapels to galleries, apartments, fountain courts, and gardens.

It's said that if you approach the Residenz Palace from one side, you'll think it's Palladian. Come in from another direction and you'll think the architectural style resembles Italian or German Renaissance.
