Saint Malo

Saint-Malo is a seaport located on the Channel at the mouth of the estuary of the Rance. This arm of the sea that turns into a river is bounded by the tidal barrage of Rance and later Wednesday by the town of Dinan-side (18 km away).

Access to the port of Saint-Malo is protected by many submerged reefs and surf at high tide by tombolos submarines (visible at low tides deep waters), in islands or islets, many of which were fortified in the seventeenth and eighteenth centuries (Cézembre, Fort Harbor, the height of the Conchée, the Grand and Petit Bé Bé, the Fort National Islet).

city of Saint-Malo was a peninsula and was surrounded by walls built and rebuilt from the twelfth to the nineteenth centuries, which architects and Simeon de Vauban Garangeau adjoignirent island fortifications. Specificity of the ramparts of Saint-Malo is that they are resting on the rock that supports the city and do that by the weight of stacked stones. Ville de Saint Malo

Saint-Malo governs the Clos-Poulet (name derived told "Pou-Alet" from the Latin Pagus Aletti, "the country Alet" but it is more likely that the name is derived from Plou / Plou-Alet "parish Alet" in Breton), which is bordered by the Rance, the Channel and the depression of Châteauneuf. The city faces Dinard. Cancale contends the east coast of the Clos-Poulet, component part of the Emerald Coast.

Today, the town also includes the former communes of Saint-Servan and Paramé with which it merged in 1967.

Tides in Saint-Malo

The tides of the Bay of Saint-Malo are among the largest in Europe. They are caused by the concentration of water in the heart of a huge triangular bay between Brittany and Cotentin.

Maximum tidal (amplitude between low tide and high tide) can reach 14 meters, more than double the regular tidal Atlantic.

It is for this reason that the barrier at the tidal plant was built precisely on the Rance (the other option is the bay of Mont Saint-Michel) in the early 1960s.
