The Marches of Brittany may one day soon be included on the UNESCO register of world heritage sites.

Among the towns participating in the project, Clisson cites its market hall and and two bridges and Clisson castle.

Clisson castle

Clisson is strategically located at the crossroads of the territories of Nantes and Poitiers.

The Middle Ages

The Marches of Brittany constituted the frontier between Brittany and France where bastions were built as a line of defence between north and south.


The city served to neutralise the power of fortresses at Tiffauges and Montaigu in the fourteenth century, when it was also home to a grisly character: Olivier V de Clisson, the famous successor to Bertrand du Guesclin wass nicknamed "the Butcher" because of his cruelty or “One-Eye” because he lost an eye in the famous battle of Auray. Olivier and Bertrand vowed fidelity to each other and sealed their commitment by the oath of Pontorson, where they drank their blood mixed in a cup!
