The New Palace is an 18th-century Baroque palace and is one of the last large city palaces built in Southern Germany. The palace is located in the center of Stuttgart on the Schlossplatz in front of the Jubiläumssäule column and Konigsbau. Public tours of the building are only permitted by special arrangement, as the building contains some government offices. Once a historic residence of the Kings of Württemberg, the New Palace derives its name from its commissioning by Duke Carl Eugen of Württemberg to replace the Old Castle in the early years of his reign. Originally, Charles commissioned Nikolaus Friedrich Thouret, but architects Leopold Retti, Philippe da la Guepière, Reinhard Heinrich Ferdinand Fischer would contribute to the design, history, and construction of the palace.
