Résumé : Between 1596 and 1611, Duke Charles de Croÿ commissioned the drawing in isometric projection and the gouache-reproduction on parchment of the towns and villages of his estate first (scattered from Picardy to Zeeland and from the Ardenne to the North Sea), and then of the provinces in which he played a role (Hainault, Tournaisis, the Lille Castellany, Namurois and Artois). In all more than 2,500 documents that were bound in about 20 albums, all recovered today to the exception of one. The presence of interpaged paper sheets in some of the albums suggests that the duke had had the intention to have these drawings accompanied by a brief comment. A correspondence between the duke and the Abbot of Anchin over 1600 and 1601 brings support to what had remained hitherto an assumption. At the same time, this paper emphasizes the importance of the work of the historian-prior François de Bar who collected and wrote a great deal of documents on the origins and the life of his abbey.
