Schönborn Palace in Heusenstamm is one of the most important Baroque buildings in the Rhine-Main region and is considered a landmark of the town. It is picturesquely situated on the edge of the old town center, surrounded by an extensive palace park with mature trees, ponds, and tree-lined avenues that emphasize the prestigious character of the complex to this day. The palace was built at the beginning of the 18th century as the residence of the Counts of Schönborn, one of the most influential noble families of the Holy Roman Empire, who held numerous high offices in church and state.
The palace was built between 1720 and 1722 under Count Philipp Erwein von Schönborn. The design is attributed to the Mainz court architect Maximilian von Welsch, who was also involved in other prestigious Baroque buildings. Typical of the architectural style of this period are the clear symmetry, the balanced structure of the facades, and the harmonious connection between architecture and landscape. The palace is a two-story building with a mansard roof, the central wing of which is particularly emphasized by a slightly projecting risalit and a richly decorated portal. Stucco decorations, sandstone elements, and the Schönborn family coat of arms above the entrance still bear witness to the high rank of its builders.
