The construction of the castle Regnéville-sur-Mer dates from the ninth century. The castle was the witness of many battles between French and English during the Hundred Years War. In the 17th century, the fortress was destroyed by order of Cardinal Richelieu. One wall of the castle flew to the bottom of the church. Today, there are only very little of the original castle (there is a tower collapsed at half) but this crypt is still beautifully preserved.

The holy wells has a square base (33m below) whose sides are oriented toward the cardinal points.
