A major fire in 1218 damaged the earlier cathedral at Amiens so badly that leaders decided to rebuild on a much larger scale. This disaster created the opening for a new, ambitious Gothic project rather than a simple repair.
In 1220, Bishop Évrard de Fouilloy launched the new cathedral project, and construction began at the crossing of the transept (the central intersection of the church plan). Starting at the center helped the builders set the key dimensions and align the nave and choir around the transept.
Master builder Robert de Luzarches directed the first stage of the building campaign. Under his leadership, the project set out a “classic” High Gothic plan with a strong emphasis on height, clear structure, and coordinated proportions across the whole church.
After the early years, Thomas de Cormont took over as master builder and carried the project forward without a break in the overall concept. This continuity mattered because it helped Amiens achieve an unusually unified design for such a large medieval building.
By the mid-1220s, work began on the sculpted portals of the west façade, designed as a major teaching surface for Christian stories and local saints. This launch of large-scale portal sculpture helped make Amiens a landmark for thirteenth-century Gothic imagery and craftsmanship.
By 1236, the nave and west façade were substantially completed, marking a major mid-project milestone. The building’s soaring interior depended on rib vaults (stone ceilings with a visible “skeleton” of ribs) and flying buttresses (arched supports) that carried heavy forces outward to exterior piers.
Amiens’ interior wall design was organized in three levels—grand arcades, triforium, and clerestory—creating a tall, visually ordered space. The nave vault rises to about 42.3 meters, showing how structural design and exterior supports were used to push height while keeping the interior relatively slender and bright.
Around mid-century, Renaud de Cormont (Thomas’s son) led a phase of reconsideration and experimentation. Builders introduced lighter, more open flying buttress designs, helping the upper walls carry more glass and appear less massive.
A fire in 1258 disrupted the campaign and damaged parts of the cathedral, including areas of the upper choir. The rebuilding after the fire left identifiable marks, especially in sections of the upper choir’s triforium on the south side, making the construction history visible in the fabric of the building.
By 1269, key work in the upper choir reached a turning point: sources link this moment to a major axial window date and suggest the high vaults were probably completed. Completing the choir vaults was crucial because the choir was the most sacred zone, reserved for clergy and central liturgical rites.
Around 1269 (often summarized as “about 1270”), the core structural campaign was essentially complete—an unusually fast pace for a cathedral of this scale. This rapid completion helped preserve stylistic unity, a key reason Amiens is often cited as one of the most coherent major Gothic churches.
In 1288, the cathedral’s nave pavement included a labyrinth with an inscription naming the principal master builders: Robert de Luzarches, Thomas de Cormont, and Renaud de Cormont. Although the original central plaque is now kept in the Musée de Picardie and what is seen today is a copy, the text preserves how later medieval viewers understood the project’s leadership and timeline.
