International Congress on Medieval Materials and Structures is a recurring scholarly conference that convenes specialists in archaeology, architectural history, materials science, conservation-restoration, and allied fields to study medieval built heritage, technology, and artefacts. The congress fosters interdisciplinary exchange among scholars affiliated with institutions such as British Museum, Vatican Museums, Smithsonian Institution, École des Beaux-Arts, and Max Planck Society, and attracts delegates from universities like University of Oxford, University of Cambridge, University of York, University College London, and Sorbonne University. It emphasizes empirical research on masonry, timber, metals, mortars, stained glass, and ceramics from contexts including Canterbury Cathedral, Chartres Cathedral, Notre-Dame de Paris, and Santiago de Compostela.

Overview

The congress addresses technical and historical questions about medieval materials through collaboration among specialists from University of Bologna, University of Leiden, University of Cologne, Heidelberg University, Princeton University, University of Chicago, Harvard University, Yale University, Columbia University, University of Toronto, McGill University, University of Barcelona, Universidad Complutense de Madrid, University of Lisbon, Trinity College Dublin, National Museum of Denmark, Rijksmuseum, Kunsthistorisches Museum, Statens Museum for Kunst, Metropolitan Museum of Art, and Louvre Museum. Topics link to case studies at sites such as Mont-Saint-Michel, Windsor Castle, Tower of London, Alhambra, and Hagia Sophia while engaging with analytical techniques developed at laboratories like CERN-partner facilities, Brookhaven National Laboratory, Los Alamos National Laboratory, and European Synchrotron Radiation Facility.

History and Development

The congress emerged from meetings among practitioners associated with institutes including English Heritage, Historic England, Cadw, ICOMOS, ICCROM, Getty Conservation Institute, Archaeological Institute of America, and Society of Antiquaries of London. Early gatherings drew contributors from projects at Sutton Hoo, Powell-Cotton Museum, Freiberg Cathedral, Ravenna Basilica, and Pisa Cathedral and referenced scholarship by figures linked to British School at Rome, French School at Rome, Danish National Research Foundation, Max Planck Institute for the Science of Human History, and the Wellcome Trust. Over successive cycles the meeting integrated methods pioneered by teams at CNRS, German Archaeological Institute, Czech Academy of Sciences, Polish Academy of Sciences, Hungarian Academy of Sciences, Institute of Archaeology of the Russian Academy of Sciences, and National Museum of China.

Conferences and Proceedings

Each triennial congress issues proceedings edited by editorial boards drawn from Balkema, Brill Publishers, Routledge, Cambridge University Press, Oxford University Press, Springer, Taylor & Francis, and Elsevier. Venues have included Leeds (linked to Royal Armouries), Florence (linked to Uffizi), Prague (linked to Charles University), Zagreb (linked to Croatian Academy of Sciences and Arts), Kraków (linked to Jagiellonian University), Lisbon (linked to MAAT), and Stockholm (linked to Nationalmuseum). Proceedings compile papers on projects related to Medina Azahara, Glastonbury Abbey, Durham Cathedral, York Minster, Bamberg Cathedral, Speyer Cathedral, and Regensburg Cathedral.

Research Themes and Methods

Core themes include materials characterization of limestone at Caen, petrographic analysis of Romanesque mortars from Siena workshops, dendrochronology of timber from Meissen and Nuremberg, isotopic sourcing of lead from Mina de Los Frailes, compositional studies of medieval glass from Toledo, experimental reconstruction of roofing techniques used at Westminster Abbey, and metallurgical examination of armours preserved at Tower of London and Musée de l'Armée. Analytical methods discussed derive from laboratories such as Natural History Museum, London, British Geological Survey, Institut de Physique du Globe de Paris, National Oceanography Centre, Scripps Institution of Oceanography, and University of California, Berkeley instrumentation facilities, including X-ray fluorescence, Raman spectroscopy, scanning electron microscopy, and synchrotron microtomography developed in partnership with European Molecular Biology Laboratory.

Notable Contributions and Case Studies

The congress facilitated landmark studies on conservation of Notre-Dame de Paris following the 2019 fire, material analyses informing restoration of Sainte-Chapelle, and interdisciplinary assessments conducted at Pomposa Abbey, Cluny Abbey, St. Peter's Basilica, Amiens Cathedral, Reims Cathedral, Burgos Cathedral, Seville Cathedral, and Zamora Cathedral. Panels have produced influential datasets used by teams at Getty Conservation Institute and Historic England on lime mortars, informed UNESCO deliberations concerning World Heritage Site nominations for Monticello-adjacent projects, and fed into policy dialogues involving European Commission, Council of Europe, and national ministries such as Ministry of Culture (France), Ministerio de Cultura y Deporte (Spain), and Department for Digital, Culture, Media and Sport.

Organization and Governance

The congress operates under steering committees populated by members of International Council on Monuments and Sites, ICOM, ICOMOS International Scientific Committee on Stone, ICOMOS-ISCS, International Standing Committee for the Studies of Stone, academic societies including Medieval Academy of America, Royal Historical Society, Society for Medieval Archaeology, European Association of Archaeologists, and regional bodies like Scandinavian University Network. Host institutions have included University of Leeds, University of Florence, Charles University, University of Zagreb, Jagiellonian University, University of Lisbon, and Stockholm University with local organization supported by municipal museums and archives.

Impact on Conservation and Heritage Practice

Outcomes influence conservation campaigns at sites managed by Historic Scotland, English Heritage, National Trust, Rijksdienst voor het Cultureel Erfgoed, and Istituto Centrale per il Restauro. Research disseminated at the congress underpins technical guidelines adopted by ICOMOS charters, informs training programmes at ICCROM and Getty, and guides laboratory-based investigations at institutions such as Victoria and Albert Museum, Ashmolean Museum, Bodleian Library, Bibliothèque nationale de France, National Library of Sweden, and Royal Library of Denmark.
