Aimé-Tilloy ou fosse Saint-Amé, located in Liévin (Pas-de-Calais), is a modern edifice built in the 19th-20th centuries. The monument is currently closed to visitors.
A steel sentinel over the land of the coalfield, the headframe of the Aimé-Tilloy pit towers above Liévin - a silent witness to a century of mining and a tragedy that plunged France into mourning in 1974.
In the heart of the Pas-de-Calais coalfield, the headframe of the Aimé-Tilloy pit - also known as the Saint-Amé pit - stands like an involuntary monument to working-class memory. Its unmistakeable latticework metal silhouette is the very embodiment of the industrial epic that has shaped northern France since the mid-19th century. To visit this site is to immerse yourself in a history that is both technical and human. The headframe, with its riveted steel beams forming an open tower structure, tells a straightforward story of post-war reconstruction, the industrial ambitions of the 1920s and the modernisation of the Mines de Lens. Its austere geometry has a raw beauty, the kind of utilitarian architecture that ends up becoming a landscape icon. But the site also carries the weight of a painful memory: the disaster of 27 December 1974, which claimed 42 victims in the underground galleries, makes it a place of remembrance as much as an object of industrial heritage. At Liévin, the headframe is much more than a mechanical structure - it is a metal cenotaph standing tall against the grey northern sky. Listed as a Historic Monument since 1992, it is part of a wider initiative to preserve the mining heritage of the Lens-Lievin basin, part of which is now a UNESCO World Heritage Site. For lovers of industrial history, photography or simply collective memory, this headframe is a must-see when discovering an area that forged modern France.
The Aimé-Tilloy pit headframe is an emblematic example of the metal industrial architecture of the 1920s. Its steel lattice structure - an assembly of riveted beams forming a network of diagonals and crossbeams - is characteristic of the reconstruction techniques adopted after the First World War in the Pas-de-Calais coalfield. This design combines structural lightness and mechanical strength, qualities that are essential to withstand the dynamic stresses associated with the movement of the extraction cables and lift shafts. The tower rises vertically above the shaft, with a rectangular plan tapering towards the top, where the extraction cable pulleys are housed. The overall impression of transparency and slenderness contrasts with the massiveness of the concrete or masonry headframes. The main uprights, made of rolled steel sections, are connected by Saint Andrew's crosses, a structural arrangement that reinforces the lateral stability of the building while giving it its distinctive graphic appearance. Around the headframe, traces of the pit floor generally remain: recipe buildings, machine rooms, lamp rooms and other technical infrastructures that make up the architectural ecosystem of an early 20th-century mining operation. This complex, albeit partial, provides a coherent picture of the spatial and functional organisation of a mining site from the classical industrial period.
