Cap Hornu is a cape located near Saint-Valery-sur-Somme, on the south bank of the Bay of Somme. The name Cap Hornu comes from the Picard word “hornu”, which means “horned” or “pointed”, and refers to the shape of the cape. The cape was also known as Cap Saint-Valery in the past. The history of Cap Hornu is closely linked to that of Saint-Valery-sur-Somme, which was a strategic port and a medieval town that witnessed many historical events. In 1066, William the Conqueror departed from Saint-Valery-sur-Somme with his fleet to invade England. In 1431, Joan of Arc was imprisoned in Saint-Valery-sur-Somme before being transferred to Rouen. In 1568, a massacre of Huguenots took place in Saint-Valery-sur-Somme after a battle between Catholics and Protestants

The Bay of the Somme or Somme Bay (French: Baie de Somme) is a nature reserve in the Somme department in northern France. This bay has an area of 70 km² and extends from Le Hourdel to Saint-Quentin-en-Tourmont. The bay is formed by the estuary of the Somme, which flows into the Channel here. A smaller river, the Maye, also flows into the bay here. The bay consists of mud flats and salt marshes, and the fresh water is carried north by the Fleuve marin côtier, a coastal current along the Picardy estuaries. The bay is rich in life forms, both marine animals, water birds, seals and the like. Sea lavender, sea wort and samphire are some of the characteristic plants on the salt marshes. The bay is also important from a cultural history point of view. For example, William the Conqueror set out from Saint-Valery-sur-Somme to conquer England. https://nl.wikipedia.org/wiki/Baai_van_de_Somme
