La charpente de la grange abbatiale de Maubuisson (Saint-Ouen-l'Aumône, Val-d’Oise)

Abstract

The roof framework of the Maubuisson Abbey bam (Saint-Ouen-VAumone, Val-d’Oise). The Maubuisson abbey bam, founded in 1237, is situated at Saint-Ouen-l’Aumone in the Val-d’Oise department. Its recent restoration by the "Monuments Historiques" provided the opportunity of studying the southern roof panel. Structural analysis of the roof space confirmed the old age of the building. Dendrochronology and a mention in the building accounts give precisions on both chronological and spatial innovations. This interpretative research, along with a complementary study of carpenter’s marks, enables us to approach the organisation of a medieval building site, and to propose an analysis of the significance of such marks. The excellent state of preservation of this wooden building offers a significative correlation between the typology of a large sized roof framework, the knowledge necessary for its conception, and the technology hence used in the first half of the century.
