Château de Bissy-sur-Fley, Historical monument and castle in Bissy-sur-Fley, France.

Château de Bissy-sur-Fley is a castle with a long rectangular walled enclosure pierced by carriage gates at both ends. The south gate is flanked by a square tower. The rectangular main building has a round tower at its northwest corner, a square tower at its southwest corner, an oblong tower at its southeast corner, and a stair tower on its facade. The complex stands on a grassy slope retained by a dry-stone wall.

The Tyard family established its presence here in 1350 when Claude de Tyard acquired the property through marriage to Françoise de Bissy. This union created a family legacy that endured across multiple generations.

Pontus de Tyard, born at Bissy in 1521, was a poet of the Pléiade and later bishop of Chalon. The castle received the Maisons des Illustres label in 2015, and the association Renaissance du château Pontus de Tyard, founded in 2001, studies and animates the site.

The castle is managed by an association that has organized guided visits since 2001 and oversees ongoing restoration work. These tours focus on the building's architecture, its literary connections, and the natural surroundings of the estate.

The castle has held the Maisons des Illustres label since 2015, awarded to places linked to notable figures. It honours Pontus de Tyard, the Pléiade poet born here in 1521, who inherited the estate in the mid-16th century after his brothers died and kept it until his death in 1605.
