The CNIT (Centre National des Industries et Techniques) is a convention center and exhibition in the middle of La Défense business district in Paris. It was inaugurated by General Charles de Gaulle on 12 September 1958, the first large building in La Défense. The man that created it dreamed of having a big exhibition center for industry, as well as existing centers and palaces within Paris, which in the end, didn't qualify. Thus arose the CNIT. In 1988 he began a great work to empty everything inside the center, increasing the total to 200,000 square meters instead of the 100,000 previously offered.
