The Castle of Chignolo Po, often called “the Versailles of Lombardy,” is one of the most magnificent country residences in the region. Its origins date back to the 13th century, though the current structure was extensively redesigned between the 17th and 18th centuries. The complex stretches along a north–south axis and includes both noble and rural courtyards, the main castle building, and a large formal garden. The central structure features a square layout with an inner portico and a medieval tower rising above it. The castle is renowned for its splendid Baroque interiors, frescoes, and stucco decorations, and for having welcomed notable historical figures such as Napoleon Bonaparte.
