Brière

Brière is a large wetland in Loire-Atlantique with a network of canals, shallow waters and peat-rich ground near Saint-Nazaire. Seven islands rise from the marsh, surrounded by reed beds and channels that collect water from the Loire.

The marsh formed over centuries through deposits the Loire River brought into the bay. During the Middle Ages, settlers began living on the islands and built dikes to manage water and harvest peat.

Local homes use reeds cut from the surrounding marsh to build their roofs, following a tradition passed down through generations. The islands hold small villages where these thatched structures still shelter families and give the landscape a particular look.

Boat rides from Rozé harbor guide visitors through the canals and provide access to bird-watching areas. In spring and autumn, water levels rise and wildlife becomes more active.

The marsh holds fossilized oak wood dug from the peat and darkened by acidic conditions over thousands of years. Artisans polish this timber and shape it into jewelry or small carvings sold in local workshops.
