Château de Marbeaumont is a castle located in the municipality of Biarne, in the Jura department of France. The castle was built in the 14th century and has undergone numerous changes over the centuries, resulting in a mix of architectural styles that range from Gothic to Renaissance.
The castle was originally built as a fortress to defend the area from invaders, and was later used as a residence for several noble families. The most notable of these families was the De Marbeaumont family, who owned the castle from the 15th to the 19th century. During their ownership, the castle underwent several renovations, including the addition of a Renaissance-style façade.
Today, the castle is open to visitors and is particularly known for its library, which contains over 12,000 volumes, including many rare and antique books. The library was established in the 17th century and is one of the oldest private libraries in France. The castle also has a collection of paintings, furniture, and other decorative arts, as well as a garden that offers panoramic views of the surrounding countryside.
