A view of the restoration works of the colonnade of Gian Lorenzo Bernini in St. Peter's Square on April 10, 2012 in Vatican City, Vatican. The square was designed by architect Gian Lorenzo Bernini in 1656. The two semi-circles of the colonnade are surrounded by 140 statues and 244 columns. Guy Devreux of the Vatican Laboratory for Marble and Cast began direction of the works in 2009. A low-voltage electric net is now mounted around the perimeter to protect the colonade from the birds nesting within the roof.
