Heuchin: Walking Routes, Faux Valley and Romanesque Heritage

Heuchin brings together features that appeal to different travel interests: hiking in the Faux Valley and a church with a distinctive architectural history. If you are looking for a hotel in Heuchin, you can decide in advance whether to focus your stay more on trails and scenery or on cultural heritage. The La Fontaine aux Faux route and the GRP Tour du Ternois Nord are important for the first focus; the Église Saint-Martin is the main cultural landmark. The differences between these themes can help you shape your itinerary. The Fontaine aux Fous is a spring in a wild gorge, associated with a medieval legend. It adds a different cultural connection to the architectural history of the Église Saint-Martin: the spring represents a story, while the church reflects specific building phases and protected parts of the place of worship in Heuchin.

Hiking and routes in Heuchin

The La Fontaine aux Faux route is a 7 km circular trail marked in yellow. It leads to a viewpoint on Mont d’Anvin, with views across the Ternoise and Bliot valleys. Its length, circular format and yellow markings give you practical details about the walk; the viewpoint adds views of two valleys. Along the route, after crossing the River Faux, you will find the small “Sculptures et jardin” garden, awarded the “Jardins des Hauts de France” distinction.

The GRP Tour du Ternois Nord passes through Heuchin.

Water and landscape

Heuchin’s waterscape can also be pinpointed. The small river Le Faux rises in Heuchin. The village lies partly in the Faux Valley; the Faulx watercourse runs through Heuchin and is 5.35 km long. Together, the source, valley and course through the village show the different ways this watercourse relates to the local landscape.

Église Saint-Martin and its architectural history

The Église Saint-Martin in Heuchin is one of the rare examples of Romanesque architecture in Pas-de-Calais. Its main building phases date from the 11th and 12th centuries and the second quarter of the 17th century; one building phase is dated to 1630. The year 1630 therefore refers to a single building phase, not to the church’s entire construction period. The listing as a Monument historique was last updated on 24 July 2026. The protected parts listed are the first two bays of the nave, the west façade and the north transept arm. A bay is a structurally defined section of the nave; the reference to the first two bays therefore identifies two specific areas.
