Located some 500 meters from the town and bridge are the ruins of a fortress/castle. The first castle was built here shortly after the year 1000 AD. It was built using earth and wood. Between the years 1200 and 1250 the first stone castle was built. In the 14th century the castle was destroyed and quickly rebuilt. But during one of the many wars between Brittany and France, in 1487 it was destroyed, yet again.

It was hastily rebuilt, but during the Wars of Religion it underwent several sieges and was pretty much destroyed. In the 18th century, they gave up the rebuilding of the castle and left it as is today.


So why build a castle in this area, and why was it attacked so often? The castle is built on rocks overlooking the Arguenon river and ford. The strategic position gave the castle owner control over the river access and the coast line, making them very powerful.

The fortress/castle can be freely visited today. There are a lot of sign posts inside the castle explaining what used to be the purpose of a particular part.

You can climb on top of the watchtower:
