The Tour du Guet is a watchtower in Calais, Pas-de-Calais, northern France. The tower is on Place d'Armes behind the Hotel de Ville. The tower is 39 metres (128 ft) in height, and has a dovecote for carrier pigeons. The tower is from 1214, when Philip I, Count of Boulogne built fortifications in the town. The tower was damaged in a 1580 earthquake. The tower was used as a lighthouse until 1848. In 1848, it became a watch tower. During World War I, it was a military post. References
