Château de Margon, Medieval castle in Margon, France.

Château de Margon is a medieval castle featuring a rectangular main building with three round towers rising three stories high. The structure displays typical medieval fortified architecture designed for both residence and defense.

The castle was built in the 12th century. The barony of Margon was attached directly to the kingdom of France in 1221, and the lord owed homage to the king at each new reign and held the right of justice. After the feudal families Alquier, de L'Isle and d'Antignac came the Plantavit de la Pauze in trade from the Renaissance, then the Le Moine family in 1719, still owners today.

The castle's name comes from the Le Moine family, financiers who acquired it in 1719 and added "de Margon"; their descendants still own it. Inside, 18th-century rooms replaced the great halls, and some walls keep painted landscapes and portraits of queens.

Visitors can explore the castle through guided tours that provide a full overview of its layout and features. Comfortable shoes are recommended since touring involves climbing multiple stories and walking through the grounds.

The garden was made in the 17th century by filling a valley floor and diverting a stream, not in the early 18th century. In 1719 arches were thrown over the moat beneath the symmetrical staircases, so the public lane (rue des Banastes) passes below while the castle connects directly to the garden above.
