Sentinel along the road, isolated in a vast field or beautiful at the end of the road, old stones suddenly appear without warning and remind us that central Brittany has been inhabited for millennia. But this archaeological heritage is fragile and non-renewable, which is why it is so precious. And to better protect it, should not we know it better? We will be delighted this 30 August to present two selected examples of the archaeological heritage of the country of King Morvan. Appointment at 3 pm in front of the Saint-Yves church in Plouray with Nathalie le Pen from the King Morvan Community Heritage Department, then possible carpooling to the 2 sites. Plan for shoes. Free.
