The Vasari Corridor was realized in only 5 months at the behest of the Grand Duke Cosimo I de 'Medici in 1565 by the architect Giorgio Vasari , who had already realized the current Uffizi Gallery. The work was commissioned to coincide with the marriage between the son of the Grand Duke, Francesco , and Giovanna d'Austria . The idea of the raised path was born to give opportunities to the grand dukes to move freely and without danger from their residence in the government building, given the still uncertain support of the population towards the new Duke and the new system of government that had abolished the ancient Florentine Republic , although the republican organs were now only symbolic for almost a century.The meat market that took place on the Ponte Vecchio was transferred to avoid unpleasant smells at the passage of the Grand Duke and in its place were moved the goldsmiths' shops that still occupy the bridge. The curiosities of this elevated passage is the turn around the torre de 'Mannelli at the end of the Ponte Vecchio, due to the strenuous opposition of the family that owns this medieval building to overthrow it. At the center of the Ponte Vecchio there are a series of large panoramic windows on the Arno towards the Ponte Santa Trinita . Of these windows, very different from the small and discreet Renaissance portholes , there were two above the central arch and Mussolini made two others in 1938 on the occasion of the official visit of <918 > Adolf Hitler (May 1938) to tighten the Axis between Italy and Germany , visiting Rome and Florence.
