The best walks and hikes around Saint-Blimont

The scenery is very beautiful, with lots of birds, cows, horses, and sheep. The road is made of pebbles and quite strenuous to ride.

It remains a strange feeling to come across traces so long after the war.

The traces of the Second World War are still omnipresent, even after 80 years.

Hourdel Lighthouse is a lighthouse on the common Cayeux-sur-Mer, it is built on the south side of the Bay of Somme, at the end of the point of Hourdel.

Here in Ault begin the chalk cliffs, which stretch all the way to Normandy and repeatedly appear as enormous cliffs.

The cliffs around the beach of Ault are composed of chalk from the Upper Cretaceous, more precisely from the Turonian and Coniacian (around 83 million years ago to 90 million years ago). They are strewn with flint nodules which highlight the subhorizontal stratification planes (the formation of flint has already been discussed in Discovery of the geology of the cliffs of Étretat, presentation of an excursion from the beach of Tilleul (Antifer) to the Porte d'Amont (Étretat Nord)). The relative proportion of chalk and flint is around 90-95% chalk to 5-10% flint. Flint horizons are stratigraphic markers. On the cliffs of Ault, the regular flint band called Seven Sisters is recognizable and characterizes the boundary between the Middle Coniacian and the Upper Coniacian (around 87 million years ago). The boundary between the lower and middle Coniacian is marked by the Shoreham 2 marl level, which is more difficult to identify. These lithostratigraphic markings allow in particular the correlation of distant deposits, such as between the Normandy and Picardy coasts, or between the French and English coasts.

The cliffs surrounding Ault beach are made of Upper Cretaceous chalk, more precisely from the terminal Turonian and Coniacian (approximately 83 Ma to 90 Ma). They are dotted with flint nodules that highlight the sub-horizontal stratification planes (the formation of flint has already been discussed in À la découverte géologique des falaises d'Étretat, presentation of an excursion going from Tilleul beach (Antifer) to Porte d'Amont (Étretat Nord)). The relative proportion between chalk and flint is approximately 90-95% chalk for 5-10% flint. The flint horizons are stratigraphic markers. On the cliffs around Ault, the regular band of flint called Seven Sisters is recognizable and characterizes the limit between the Middle Coniacian and the Upper Coniacian (approximately 87 Ma). The boundary between the Lower and Middle Coniacian is marked by the Shoreham 2 marl level, which is more difficult to identify. These lithostratigraphic markers allow in particular the correlation of distant deposits, such as for example between the Normandy and Picardy coasts, or between the French and English coasts.

The church is built of natural stone with a characteristic pattern. It consists of two naves, separated by high arches. The baptismal chapel is still part of the original church. A church was first mentioned in the 12th century, but the current church dates back to the 13th century. The church was repeatedly destroyed during the Hundred Years' War and was set on fire in 1475, when the city defended itself against the English and Burgundian rulers. The church was rebuilt at the end of the 15th century and reconsecrated in 1500, but construction activities lasted until 1559. During the French Revolution, the furniture was sold, shrines and paintings were burned and bells were melted down. In 1845, a rectangular brick building was built next to the tower. Next to the church is the heavy tower, equipped with buttresses. In 1786, it was crowned with a tent roof.
