In 1717, the French engineer Chaussegros de Léry designed the plans for the Citadelle de Quebec, but the construction began a hundred years later, in 1820, by the British administration. The construction of the Citadelle only lasted for eleven years and ended in 1831.
Chaussegros de Léry, who did the plans, was inspired by the star-shaped fortifications in the citadel of Saint-Martin-de-Ré, in France.
