This greenway was built on the old railway line which linked Châteaubriant to Ploërmel. In its heyday at the start of the last century, trains were essentially freight trains that transported iron mined in the region.

Very beautiful castle allowing you to see the evolution of architecture throughout history. It is one of the rare castles where we find the medieval part with its keep, drawbridge, watchtower on the walls..., a barrel part with brick and clay arcades and a renaissance part with the bedroom by Françoise de Foix.

Until now I thought that Châteaubriand was only a writer. In fact, René de Châteaubriand was born in Saint-Malo, and died in Paris in 1848. In short, it is not certain that he passed through this city, but in any case he comes from this great French family. The town takes its name from Brient, the lord who founded the castle in the 9th century.

Around 1050, Lord Brient built a wooden castle on a rocky promontory, at the confluence of the Chère and the Rollard. Between the 12th and 15th centuries, Chasteau Brient developed and became a formidable stronghold in the Marches of Brittany. The keep, the dwellings and the ramparts still evoke the power of this medieval castle. From the 1490s, Françoise de Dinan (1436-1500) chose to take over the former courtyard of the castle to build a vast residential complex there and lay out gardens. She initiated this project but it was her grandson Jean de Laval (1487-1543) who completed it, drawing inspiration from architectural research and the effervescence of the Renaissance. Built in the 1530s, the golden room is the only interior of the Renaissance complex accessible all year round. Reorganized a century later, this room retains a coffered ceiling and a remarkable set of woodwork. Françoise de Foix (1495-1537), wife of Jean de Laval, dies
