The Acheneau

Highlight • River

A place on the bridge overlooking the Acheneau river. The river is 30 km long. An interesting point is that this watercourse has such a slight slope that its course can be reversed when sufficiently high tides influence the river level. Human control of this river and the marshes of the southern Loire began especially under the influence and control of the Cistercian monks of the abbey of Buzay from the 12th century.

Window over Lake Grand-Lieu

Highlight • Other

The lake is a natural site and an ornithological reserve and its access is very limited to the public. There are not so many views on this one. You can find them on the lacdegrandlieu.com website

Port of Collet

Highlight • Other

For centuries, the port of Collet was the main point of departure for the export of salt produced in the salt marshes of the coast. At the end of the 15th century, more than 200 ships loaded in the bay of Bourgneuf (then known as “bay of Brittany”). Gradually, the siltation of the bay causes the end of the activity.
Thanks to a lock built in 1879 which regulates the waters of the Marais and those of the sea, the port's activity can continue around oyster farming and yachting.

Pré Vincent Beach

Highlight • Beach

Facing south, Pré-Vincent beach is cut by numerous groynes of wood or rocks. At low tide, the sea retreats several kilometers and gives way to the famous mud from the Bay of Bourgneuf. Near the town center of Moutiers en Retz, the beach is bordered by a promenade exclusively reserved for pedestrians. Pretty silted walk when I hiked it.

Chapel of Prigny

Highlight • Religious Site

Prigny, is actually the old village of Moutiers-en-Retz, and this chapel was the first church of Moutiers, because until the end of the Middle Ages, Moutiers were only a simple suburb of Prigny. Located on the former shore of the Gulf of Machecoul, Prigny was then a fortified town overlooking the Breton marshes.
This building is now called a chapel by the inhabitants, simply because of its small size. Dating from the 11th century, the chapel of Prigny is a squat building in the primitive Romanesque style.
It is currently the subject of a restoration program.
