The New Palace is an 18th-century Baroque palace in Stuttgart and is one of the last large city palaces built in Southern Germany. The palace is located in the on the Schlossplatz in front of the Jubiläumssäule column and Königsbau. 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 Leopoldo Retti, Philippe de La Guêpière, Reinhard Heinrich Ferdinand Fischer would contribute to the design, history, and construction of the palace.
