Francis, Duke of Guise
Place d'Armes is one of the largest squares in the city of Calais. It adjoins the watchtower, and during medieval times was once the heart of the city. While Calais was a territory of England (1347–1558), it became known as Market Square (place du Marché). Only at the end of English rule did it take the name of Place d'Armes. After the reconquest of Calais in 1558 by Francis, Duke of Guise, Francis II gave Calais the right to hold a fair twice a year on the square, which still exists today, as well as a bustling Wednesday and Saturday market.
