The rocks, with their cracks and small caves in the calcareous wall, provide an important nesting site for numerous bird species such as jackdaws, house martins, fulmars, kestrels, gulls, terns and herring gulls. As part of a renaturation project in 2006, a section of the asphalt road leading to the summit and the parking spaces there were completely removed. Instead, a parking lot about 300 meters inland was significantly expanded.

The obelisk crowns a 133-meter-high ensemble on a pedestal that can be seen from afar. It is THE landmark to reach to enjoy a 360° panorama from the top of the cliffs of Cap Blanc Nez. When the German army took possession of the Opal Coast in May 1940, this monument was immediately destroyed. The current Dover Patrol dates from the early 1960s. The last restoration took place in 2007. Source: https://www.calaisxxl.com/de/offres/a-voir-a-faire/monument-a-la-dover-patrol/

Excavations carried out before the construction of a car park on Mont d'Hubert, near Cap Blanc Nez (Pas-de-Calais), have uncovered the remains of a Middle Neolithic camp (4,200 to 3,800 years before our era). The camp, covering three hectares, surrounded by a ditch and visible from more than thirty kilometers away, has yielded remains of animal and human bones, ceramics and flints.

The bomb holes in the surrounding pastures still bear witness to the English bombings, particularly around Mont d'Hubert. Wild orchids abound in these vast limestone meadows... perhaps you will meet the Boulogne sheep in charge of maintaining these protected areas? As part of the implementation of the NATURA2000 objectives document, this itinerant sheep grazing is carried out each year from May to October. The EAFRD, by financing the shepherd position, allows 600 sheep to roam all of the lawns to restore natural habitats.

The Dover Patrol was a Royal Navy command during World War I, whose main task was to prevent German ships, mainly submarines, from crossing the Channel into the Atlantic Ocean. It consisted of several naval ships and aircraft, and performed various tasks, including anti-submarine patrols, escorting ships, laying and clearing naval mines, and bombing German military positions. After the war, memorials were erected in memory of the Dover Patrol in various locations including Dover, Cap Blanc-Nez and New York.
