Fort Carré, often called the Fort Carré d'Antibes, is a 16th-century star-shaped fort of four arrow-head shaped bastions that stands on a 26-meter high promontory in Antibes, France. Henry II ordered construction of the fort in the 16th century at a time when Antibes was situated on a tense border with the Duchy of Savoy. During the 17th century, the Marquis de Vauban redeveloped it. The Fort was decommissioned in the early 20th century.
