Basilica of the Sacred Heart (Brussels)

Brief Information

Brussels’ Sacré-Cœur did not begin as a church: Leopold II first wanted a Belgian Pantheon on Koekelberg Hill, but after a trip to Paris he replaced the idea with a national shrine dedicated to the Sacred Heart of Jesus. This is why the building is important not only for its size, but also for the shift in its concept: a monument to “great Belgians” became a pilgrimage basilica.

Its present appearance is also the result of a change in direction. The first design was Neo-Gothic, but after the First World War it was not resumed because of financial problems. Instead, Albert Van Huffel’s design was adopted, resulting in the largest Art Deco building in the world. The long construction, interrupted by two wars and completed in 1969, is legible in the very idea of the building: it looks like a monument of the twentieth century, not like a medieval cathedral.

What to Notice First

It is worth comparing three things: mass, materials, and the vertical silhouette. The basilica stands in Elisabeth Park on the top of Koekelberg Hill, so its two towers and green copper dome act as a landmark on Brussels’ northwestern skyline. The dome’s height of 89 meters matters not in itself: it explains why the building is perceived as part of the urban landscape, not only as a facade.

The materials show why this is Art Deco rather than a continuation of the Neo-Gothic project. The structure combines concrete reinforced with terracotta layers, brick, and individual stones; this mixture gives it massiveness without Gothic stone tracery. Inside, a separate focus is created by Anto Carte’s eight stained-glass windows with episodes from the life of Jesus. They are worth mentally comparing with the heavy body of the building: the religious subject here is placed within architecture that speaks the language of concrete, brick, and large-scale geometry.
