The ideas expressed in the new urban quarters were also superimposed on the old, in the form of new streets cut through the medieval fabric to link key buildings with gates, ports, or barracks, such as the Via Toledo in Naples, constructed to enable soldiers from the Spanish garrison to move into the city at times of unrest, or the construction of the Uffizi palace in Florence by the Medici grand dukes of Tuscany. These new streets were interrupted by squares decorated with neoclassical monuments and statues, whose main purpose was to increase the visual impact of the imposing buildings beyond. All commercial activity was rigorously excluded.
