This paper presents a set of algorithms dedicated to the 3D modeling of historical buildings from a collection of old ar-chitecture plans, including floor plans, elevations and cut-offs. Image processing algorithms help to detect and local-ize main structures of the building from the floor plans (thick and thin walls, openings). The extrusion of the walls allow us to build a first 3D model. We compute height informations and add textures to the model by analyzing the elevation im-ages from the same collection of documents. We applied this pipeline to XVIII th century plans of the Château de Versailles, and show results for two different parts of the Château.
