Chateau de Sceaux is a historic castle located in the town of Sceaux, in the southern suburbs of Paris, France. Originally built in the 17th century for the Colbert family, it later became the residence of the dukes of Trévise and was extensively renovated by architect Jules Hardouin-Mansart in the 18th century.

The castle is built in a classic French architectural style, with a symmetrical layout, tall slate roofs, and elegant stonework. The interior is lavishly decorated with artwork, tapestries, and antique furnishings, including a collection of 18th-century French furniture.

The castle is surrounded by a large park, which includes formal gardens, a pond, and wooded areas. The gardens were designed by André Le Nôtre, the famous landscape architect who also designed the gardens at Versailles. The park is a popular destination for locals and tourists alike, who come to stroll, picnic, or simply relax in the tranquil surroundings.

Today, Chateau de Sceaux is open to the public for guided tours, which provide an insight into the castle's history and architecture. The castle also hosts a range of cultural events, including concerts, art exhibitions, and theater performances. It is a popular destination for weddings, corporate events, and other special occasions, and is widely regarded as one of the most beautiful castles in the Paris region.
