Château du Val, Royal hunting lodge in Saint-Germain-en-Laye, France.

Château du Val is a 17th-century classical castle at the northern end of the Grande Terrasse in Saint-Germain-en-Laye. Its pale yellow stone facade has three levels: three arched windows and an arched door on the ground floor, four rectangular windows above, and a dark grey mansard roof with dormer windows and a balustrade. A flagpole stands in front.

Jules Hardouin-Mansart built this residence in 1674 for King Louis XIV, replacing a simple hunting lodge with an elegant structure. The building reflects royal ambitions to develop the northern area of Saint-Germain-en-Laye.

The name Val comes from the hunting relay that stood here in the forest of Saint-Germain. In 1778 the Prince de Beauvau-Craon received Benjamin Franklin at the château. Since 2021 the building has been run as a hotel under the commercial name la Maison du Val, and only one of the four ground-floor salons keeps its 17th-century decoration.

The château stands at the northern end of the Grande Terrasse, a straight tree-lined promenade in the forest of Saint-Germain-en-Laye. The building is now a four-star hotel under the name la Maison du Val, so the house and its grounds are not a public monument; access is for guests and event visitors. The forecourt with its gravel and grass is visible from the terrace.

The four ground-floor salons were grouped around a single shared stove, and only one of them still keeps its 17th-century decoration. In 1778 the prince de Beauvau received Benjamin Franklin at the Val. The gardens are attributed to André Le Nôtre, and a machine by Arnold de Ville and Rennequin Sualem raised Seine water from the Pallefour mill to feed them.
