La Grande Arche, Paris, France | 2019 4K

A great national design competition was launched in 1982 as the initiative of French president François Mitterrand. Danish architect Johan Otto von Spreckelsen (1929–1987) and Danish engineer Erik Reitzel (1941-2012) designed the winning entry to be a late-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 in 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 Grande Arche is in the approximate shape of a cube with a width, height and depth of 110 m (360 ft); it has been suggested that the structure looks like a hypercube (a tesseract) projected onto the three-dimensional world.[2] It has a prestressed concrete frame covered with glass and is covered in Bethel Granite and was built by the French civil engineering company Bouygues.
