Huby-Saint-Leu between nature and heritage

Huby-Saint-Leu brings together natural landscapes, local history and a direct connection to the Ternoise. The Marais communal d’Huby-Saint-Leu represents wetlands and plant life; Église Saint-Leu combines a history of construction dating back to the 16th century with furnishings from the 19th century. Anglers can also enjoy the stretch of the Ternoise running from Grigny to its confluence with the Canche in Huby-Saint-Leu. These different highlights can help you choose Huby-Saint-Leu based on the theme that shapes your trip.

The communal marsh and natural landscape

The Marais communal d’Huby-Saint-Leu is classified as a continental ZNIEFF (Natural Zone of Ecological, Faunistic and Floristic Interest) type 1. The corresponding entry was updated on 12 June 2024; the area covers 5.91 hectares. Its plant life includes six species of interest for the ZNIEFF, including three regionally protected species. The classification, area and species numbers offer different points of reference for the wetland: a formal category, a clearly quantified size and botanical details.

Église Saint-Leu: construction history and heritage status

Église Saint-Leu was built in 1506 with the support of François de Créquy. François de Créquy was Lord of Huby and Governor of the Boulonnais. The church features Gothic architecture. Its furnishings include two 19th-century paintings donated by the Bordes-Châtelet family. It is listed as a historic monument under a decree dated 5 April 1930; the national notice was amended on 24 July 2026. The building, furnishings and protection status belong to different periods: 1506 refers to the construction of the church, the 19th century to the paintings and 1930 to the decree; the 2026 amendment concerns the later notice.

The Ternoise and fishing

The fishing stretch on the Ternoise runs from Grigny to its confluence with the Canche in Huby-Saint-Leu. There is also a designated no-kill fly-fishing stretch at the confluence, where hooks with pinched-down barbs are required. The longer stretch should be distinguished from the separately designated section subject to this hook rule. The fishing information is based on the 2026 regulations of the Pêcheurs Hesdinois; seasonal rules may change. Check the conditions applicable during your visit before fishing.

Landscape between the 7 Vallées and the forest

Huby-Saint-Leu lies in the heart of the 7 Vallées. The forest lies on the summit and southern slope of a low plateau that forms the edge of the Artois anticline. To the south, the plateau overlooks the valleys of the Ternoise and the Canche; to the west, it overlooks the Planquette valley. Beech (60%) and hornbeam (25%) dominate the forest, which is also home to roe deer, rabbits, woodcocks and pheasants. Unlike the marsh, which is described in terms of its area, the forest draws attention to its elevation, slope and the valleys overlooked by the plateau.
