Balleroy Castle is a grand chateau located in the town of Balleroy in Normandy, France. The castle was built in the 17th century by the architect Francois Mansart for Jean de Choisy, who was a member of the court of King Louis XIII. The castle is considered one of the most beautiful examples of 17th-century architecture in France.

The castle is situated on a hill overlooking the surrounding countryside, and it was designed to be both a fortress and a comfortable residence. The castle's most notable feature is its octagonal tower, which is topped with a pointed roof and a spire. The tower is surrounded by a moat and is connected to the main building by a bridge.

The castle's interior is equally impressive, with several grand salons, a chapel, and an impressive collection of artwork and antique furniture. The castle also features beautiful formal gardens, which were designed by Andre Le Notre, who was also responsible for the gardens at Versailles.

During World War II, the castle was occupied by German forces, who used it as a headquarters for their military operations. After the war, the castle was restored to its former glory, and today it is open to the public as a museum. Visitors can explore the castle's rooms and gardens and learn about the history of the area and its significance in French history.
