The Great Arch backdrop

The Great Arch 2025 Directed by Stéphane Demoustier L'Inconnu de la Grande Arche

1983. The biggest architectural competition in history, both anonymous and open, is launched under the impetus of a new socialist president, François Mitterrand. Coveted by all the biggest international architectural firms, the competition is surprisingly won by an unknown: Johan Otto von Spreckelsen, an architecture teacher from Copenhagen. Until then, the fifty-year-old Danish had only built 4 buildings: his home and three small chapels.
