Saint-Valery-sur-Somme is the most beautiful town on the Bay of the Somme. It was a well-known harbor in the Middle Ages (William the Conqueror would have left here in 1066 to England for the battle of Hastings). The town consists of 2 parts. The lower part is along the Somme, with a marina. In the upper city, the historical part, numerous historic buildings can be found: the Porte Jeanne D'Arc (Porte du Haut), named after the heroine who was in Saint-Valéry in 1430, the église Saint Martin (12th century), the Castle that dominates the town and the Abbey, which was founded by the students of Saint-Valéry and was visited by Charlemagne (in 800 AD).
In the small streets of the upper city you will find a true 'herbarium'. Along the streets are numerous plants, some with remarkable anecdotes. This herbarium was built by the Sisters of the Hospital and still provides a sometimes colorful spectacle.
Just outside the town is the Chapel of the Mariners on top of a hill. The Romanesque chapel was built on the site where according to tradition Saint-Valéry lived (in the 7th century AD). You have a beautiful view over the bay of the Somme with Le Crotoy on the other side. When you walk past the chapel, you come to the Cap Hornu (including a hotel that we can highly recommend). You can walk back along the coast back to Saint-Valéry-sur-Somme. A walk of four kilometers.
