The Grande Arche de la Fraternité is a monument in the business district of La Défense to the west of Paris. It is usually known as the Arche de la Défense or simply as La Grande Arche. An international design competition was launched at the initiative of French president François Mitterrand. Danish architect Johann Otto von Spreckelsen (1929–1987) designed the winning entry to be a 20th century version of the Arc de Triomphe: a monument to humanity and humanitarian ideals rather than military victories. After Spreckelsen's death in 1987, his associate, French architect Paul Andreu, completed the work. The Arche is almost a perfect cube (width: 108m, height: 110m, depth: 112m. The two sides house government offices. The roof section, exploited by is an exhibition centre.
