Arnaud Ybert

Arnaud Ybert serves as a Lecturer in medieval art history at the University of Western Brittany, where he is affiliated with the Breton and Celtic Research Center (CRBC). His academic work centers on Gothic architecture, with a focus on construction methodologies and structural design in medieval religious buildings across France, particularly Brittany.

Ybert's research spans Medieval Art History, Gothic Architecture, and Medieval Building Techniques. He specializes in technical aspects including scaffolding systems, vaulting techniques, polylithism in Breton cathedrals, and archaeological analysis of construction processes. His work integrates material science with architectural history to reconstruct medieval building practices and understand structural evolution in religious monuments.

His publication record (2014-2023) demonstrates consistent focus on French Gothic cathedrals (Notre-Dame, Chartres, Beauvais) and Breton religious structures. Key themes include construction challenges, restoration methodologies, fire impacts on heritage, and regional architectural variations. The 2023 monograph on Saint-Mathieu de Fine-Terre synthesizes 25 years of archaeological research on a pivotal Breton abbey.

Ybert co-leads research axis 2 (De la création au remploi) and participates in axis 3 (Conscience(s) du maritime) and the transversal pole Sources and resources at CRBC. Since 2019, he co-organizes a seminar on lapidary ensembles with Yvan Maligorne and contributes to excavation reports for Grandmont Abbey. He is an active member of the Gdr ReMArch research network focused on medieval architectural studies.

His primary research base is the Breton and Celtic Research Center (CRBC), where he collaborates on interdisciplinary projects examining maritime consciousness and material reuse in historical contexts. Current work emphasizes the integration of archaeological evidence with architectural analysis for heritage preservation.
