This wealthy residence on the edge of the forest of Saint-Germain en Laye was designed by Jean René de Longueil in a strategic location, precisely on the path leading the king from the Château du Louvre to the Château de Saint-Germain en Laye. The idea was ingenious: to meet the king by offering him a short break during his journey.

The nobleman then called on Mansart to build the edifice, which was inaugurated in April 1651 at a celebration for the young Louis XIV. With this strategy, Jean René de Longueil was confident of winning the king's good graces. He even went so far as to reserve a wing of the building for him, with theKing's Apartment, including a ballroom designed for the Sun King, as well as a bedroom with an interlocking domed ceiling. Discover almost 300 years of history with activities for young and old!
