La Grande Arche de la Défense (pronounced: [la gʁɑ̃d aʁʃ də la defɑ̃s]; also La Grande Arche de la Fraternité) is a monument and building in the business district of La Défense and in the commune of Puteaux, to the west of Paris, France. It is usually known as the Arche de la Défense or simply as La Grande Arche.

A great national design competition was launched in 1982 as the initiative of French president François Mitterrand. Danish architect Johann Otto von Spreckelsen (1929–1987) and Danish engineer Erik Reitzel 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. The construction of the monument began in 1985. Spreckelsen resigned on July 1986 and ratified the transfer of all his architectural responsibilities to his associate, French architect Paul Andreu. Reitzel continued his work until the monument was completed in 1989.
The Arche is in the approximate shape of a cube (width: 108m, height: 110m, depth: 112m); it has been suggested that the structure looks like a hypercube (a tesseract) projected onto the three-dimensional world. It has a prestressed concrete frame covered with glass and Carrara marble from Italy and was built by the French civil engineering company Bouygues.
La Grande Arche was inaugurated in July 1989, with grand military parades that marked the bicentennial of the French revolution. It completed the line of monuments that forms the Axe historique running through Paris. The Arche is turned at an angle of 6.33° on this axis. The most important reason for this turn was technical: With a métro station, an RER station, and a motorway all situated directly underneath the Arche, the angle was the only way to accommodate the structure's giant foundations. From an architectural point of view, the turn emphasizes the depth of the monument, and is similar to the turn of the Louvre at the other end of the Axe historique.
In addition, the Arche is placed so that it forms a secondary axe (axis) with the two highest buildings in Paris, the Tour Eiffel and the Tour Montparnasse.
The two sides of the Arche house government offices. The roof section is an exhibition centre. The vertical structure visible in the photograph is the lift scaffolding. Views of Paris are to be had from the lifts taking visitors to the roof. (After a non-injury accident in the elevators in April 2010, the Department of Ecology, owner of the roof of the Grande Arche, has decided to permanently close the computer museum, restaurant, and viewing deck. Access to the roof is still possible via the elevators in the north and south walls, but they are closed to the public.)[1]
