Clisson (Breton: Klison), is a village in the Loire-Atlantique département in western France. It is situated at the confluence of the Sèvre Nantaise and the Moine 17 miles (27 km) southeast of Nantes.
The town and the celebrated family of Clisson, the most famous member of which was Olivier IV de Clisson, take their name from their stronghold. Clisson has its imposing ruins, parts of which date from the thirteenth century. The town and castle, the château de Clisson, were destroyed in 1792 and 1793 during the War in the Vendée.
Afterwards, the sculptor François-Frédéric Lemot bought the castle, and the town was rebuilt in the early part of the 19th century according to his plans. There are picturesque parks on the banks of the rivers. The Moine is crossed by an old Gothic bridge and by a fine modern viaduct.
