Sancarlone

The San Carlone or Sancarlone or the Colossus of San Carlo Borromeo is a massive copper statue by Giovanni Battista Crespi, erected between 1614 and 1698, near Arona, Italy. It represents Charles Borromeo, a Catholic saint and former archbishop of Milan. According to sculptor Frédéric Auguste Bartholdi "The statue of St. Charles Borromeo is the first known example of a statue of repousse copper, worked with the hammer inside and outside, and freely supported on iron beams". Today, the complex is maintained by Milan's Biblioteca Ambrosiana.
