National Basilica of the Sacred Heart

The National Basilica of the Sacred Heart is a Roman Catholic Minor Basilica and parish church in Brussels, Belgium. The church is dedicated to the Sacred Heart, inspired by the Basilique du Sacré-Coeur in Paris. Symbolically, King Leopold II laid the first stone of the basilica in 1905 during the celebrations of the 75th anniversary of Belgian independence. The construction was halted by the two World Wars and finished only in 1969. Belonging to the Metropolitan Archdiocese of Mechelen–Brussels, it is one of the largest churches by area in the world.

Located in the Parc Elisabeth atop the Koekelberg Hill at the border between Brussels' Koekelberg and Ganshoren municipalities, the church is popularly known as the Koekelberg Basilica. The massive brick and concrete reinforced church features two thin towers and a green copper dome that rises 89 metres above the ground, dominating Brussels' northwestern skyline. It is served by Simonis metro station on lines 2 and 6 of the Brussels metro.
