Abstract: Dedicated to the 579,606 militaries (all countries and all grades) fallen during the First World War in the North of France, the Memorial of Notre-Dame-de-Lorette is a large elliptic ring in UHPFRC (BSI-Ceracem®). The perimeter of the ellipse (328 m) is composed with 122 precast elements and prestressed for 49 of them. The horizontal ring is for the two third buried in the slope of the topography and for one third in cantilever (prestressed hollow-cored beam). From the beginning, the memorial was designed with the UHPFRC. The choice of this material is due to durability required and to performances necessary for bridging the curved span of 60 meters. All details were adapted to maximize the capacities of the material, both in terms of structure and expressivity. This paper first presents the requirements of the project and the architectural proposal of Philippe Prost. Then the paper describes the technical details and explains why the UHPFRC is particularly adapted for this project. In conclusion, a reflection is made on the feedbacks of this emblematic project.
