A monumental Art Deco basilica crowned by a towering green copper dome, dominating Brussels’ north-western skyline and ranking among the world’s largest churches by area.
At a glance
Belgium’s largest church stands atop the Koekelberg Plateau, its 89-metre dome visible across the city. The Catholic minor basilica belongs to the Metropolitan Archdiocese of Mechelen–Brussels and serves as a parish church, drawing pilgrims to its Art Deco-Byzantine interior.
History
King Leopold II laid the basilica’s first stone in 1905, marking the 75th anniversary of Belgian independence. The massive project was interrupted by both world wars, with construction eventually completed in 1970—a 65-year undertaking that reflected Belgium’s evolving architectural ambitions.
What you see
The basilica’s dominant feature is its nearly 89-metre green copper dome, rising above a structure of brick and reinforced concrete. Two thinner towers flank the composition. The Art Deco exterior, with neo-Byzantine elements, creates a distinctive silhouette that has shaped Brussels’ north-western profile for decades. Inside, the scale is overwhelming—at the 17th largest church by area globally, the interior volume commands attention.
Cultural significance
Symbolically linked to the Parisian Basilique du Sacré-Cœur, this Brussels basilica embodies early 20th-century Belgian religious confidence and urban identity. Its completion after two decades of interruption marked a return to peacetime ambition and spiritual renewal in post-war Europe.
