Court architect Alessandro Galli da Bibiena, who came from a family of artists in Parma, created a connection between the palace and the two parts of the settlement, the upper village and the lower village of Schwetzingen, by laying out the market square (later the palace square). The square has twice the depth of the cour d'honneur. His activities at the palace are documented in 1718 with the plans for the old orangery and the northern circle building in 1748.
