Facade of the cathedral basilica

This term, which is perhaps a little difficult to understand these days, means that from the beginning, through the grace of God, the Mother of God was freed from the burden of original sin - which every human being carries within themselves. The feast “Maria - Immaculata Conceptio” of the Immaculate Conception of Mary (in the Catholic liturgy it is correctly said: “Solemnity of the Virgin Mary, Mother of God, conceived without original sin)” is celebrated on December 8th.

In 1879 a new fortress was built. It is the most northerly of four fortresses that were supposed to protect the port of Boulogne-sur-Mer. The forts consisted of a barracks, an ammunition warehouse, some artillery platforms, and a well. The fortress was surrounded by a stone wall and a dry moat.
During the First World War, the fort was operational and also played a logistical role. The fortress was modernized during the two world wars. On May 23, 1940, the battery resisted the German troops, but had to give up the fight when the ammunition ran out.
The occupying forces took possession of the fort and fortified it in 1944. On 21 and 22 September 1944 the fort was recaptured by Canadian troops.

Incredibly beautiful paths - partly on wooden planks, partly through fine sand. A small, hidden natural paradise that can be wonderfully explored on a circular hike.

Do not miss. Don't hesitate to go down into the crypt. Don't forget to look up inside the dome! Notre-Dame de Boulogne has a great history that you will be able to discover or rediscover with pleasure

Family-friendly walk through a vulnerable dune area near the Slack river. Not suitable for wheelchairs. The route is well marked. The dunes themselves are not accessible due to their fragile nature, so you are obliged to follow the provided paths. The stretch of beach between Ambleteuse and Wimereux is impressive.
