The origins of this Gothic structure date back to the 13th century. Despite various alterations in subsequent centuries, the castle retained its original feudal character. It served for a long time as the residence of the Montesquieu family and was the place where the legal philosopher wrote a large part of his works. Since 2008, the entire estate has been a protected monument.
