The Second Vatican Council (1962–1965) saw the Catholic Church modernise in a bid to bring itself into line with a changing world and attract new followers. Religious architecture started to adopt a pared-back aesthetic in which a welcoming feel took precedence over pomp and splendour. This is reflected in Notre-Dame du Blankedelle Church, which was consecrated in 1970. Built to a design by Brussels architect Albert Debaeke and Parisian architect Pierre Pinsard, the church is divided into two sections, the first in ochre brick contrasting with another cubic, recessed structure. The church is extended on either side by several brick buildings arranged in a U shape around a small courtyard. A reinforced concrete bell tower stands out prominently from the rest of the complex. Inside, particular attention is paid to natural light, essential for creating a sacred atmosphere. The ambulatory is bordered by a colonnade of square concrete shafts. A translucent glass frieze runs around the perimeter of the space, with a second highlighting the ceiling, which looks as if it is suspended. Meanwhile, the altar is illuminated by an overhead skylight, emphasising its spiritual character. For the sake of authenticity, the materials – brick, concrete and blue limestone – have been left bare and the construction system is clearly visible. The organ in the choir was built by Patrick Collon in 1981.
