Description on this project

In the spring of 2009, the largest restoration ever undertaken of the colonnades is built in the 17th century by Bernini, occupied more than 100 conservators, scientists, and engineers using the most modern techniques. They are thus able to bring to their former glory 88 pillars, 284 columns, and 140 statues of saints surrounding the square, which forms part of the border between the Vatican and the Italian states. The Studio Croci & Associati in Rome is commissioned to design an intervention that provides for the complete demolition of the floor in question and the subsequent reconstruction of the same by means of prefabricated slabs prestressed concrete.
