Impressive chalk cliffs

From here you have a great view over Ault

The cliffs are made of chalk and are impressive to look at.

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.

Listed as a Historic Monument, the Notre-Dame church is a very interesting building that expresses some very characteristic features of the architecture of the Norman School, particularly in the Gothic choir attributed to the 13th century. The bell tower-porch has a late 15th century portal with an ogival arcade that frames an openwork tympanum. Above the portal is built a flamboyant style rose window. The nave, flanked by two side aisles, was built in the 13th century, but was extensively remodeled in the 16th and 17th centuries. It has an interior elevation on 3 levels. All that remains of the primitive Romanesque church is the base of the old lantern tower. Visible only from the outside, it is located at the crossing of the transept. The church has some singularities: -The sepulchre dating from the 15th century, representing Christ stretched out on a shroud, Nicodemus, Joseph of Arimathea, Saint John the Evangelist, the Virgin Mary and Mary Magdalene. -The stained glass windows are attributed for the most part to Édouard Didron, a great Parisian master glassmaker.
