Abstract
Abstract. Our multidisciplinary team has virtually reconstructed the greatest church of the Romanesque period in Europe. The third church of the Abbey of Cluny (12th c.) has been destroyed after the French Revolution, leaving only 8% of the building standing. Many documents have been studied, to include the latest archaeological knowledge in the virtual model. Most remains have been scanned for CAD restitution. The mock-up of the church needed 1600 different numerical files, including the scanned pieces and the anastylosis of a Romanesque portal, a Gothic façade and a mosaic pavement. We faced various difficulties to assemble the different elements of the huge building, and to include the digitized parts. Our workflow consisted in generating geometrical shapes of the church, enriched with metadata such as texture, material... The whole mock up was finally exported to dedicated software to run the rendering step. Our work consisted in creating a whole database of 3D models as well as 2D sources (plans, engravings, pictures...) accessible by the scientific community. The scientific perspectives focus on a representation in virtual immersion of the grand church at scale 1 and an access to the digital mock-up through Augmented Reality.
Highlights
The Romanesque church of Cluny was the greatest of all Europe and designated as the “Second Rome”
On the technical aspect the challenge for the engineers was to create a digital model according to the latest scientific researches, including the archaeological excavations and the remains including the study of the documentary sources

Summary
The Romanesque church of Cluny was the greatest of all Europe and designated as the “Second Rome”. Located at the frontier of the German Empire and the French Kingdom, the abbey of Cluny played a very prominent role in the history of Medieval Ages, from its foundation in 910 to the end of the 12th century. Three different aspects justified this task, on one hand the touristic affluence and the difficulty to understand the archaeological remains called for a virtual restitution. On the technical aspect the challenge for the engineers was to create a digital model according to the latest scientific researches, including the archaeological excavations and the remains including the study of the documentary sources. This implied the use of special algorithms to offer the best restitution of the architecture. The engineering school of Arts et Métiers has developed for this task the Gunzo project, a multi disciplinary research team
