Calder and Louisa fly from Paris to Monaco to see his monumental standing mobile Quatre lances, recently installed above a pool on the esplanade of the Centennial Hall. They attend the dedication on the morning of 20 December with Princess Grace and Prince Rainier, returning to Paris that afternoon.
In 1963, Calder completed construction of a large studio overlooking the Indre Valley. With the assistance of a full-scale, industrial ironworks, he began to fabricate his monumental works in France and devoted much of his later working years to public commissions. Calder died in New York in 1976 at the age of seventy-eight.
