Carleton Martello Tower
⎯⎯⎯
Tour Martello Carleton
Construction of this tower was begun by the British Army during the War of 1812 as one of the projected series of fortifications intended to block the western land approach to Saint John. Subsequent to its completion in 1815 the tower was largely neglected, seeing only occasional use in times of emergency, including service as a fire control headquarters in the second world war. The original structure typifies the English martello tower design, a popular form of coastal defence in the British Isles during the Napoleonic period.
L’armée britannique entreprit l’érection de cette tour pendant la guerre de 1812 en vue de protéger l’entrée de Saint-Jean d’une attaque qui viendrait de l’ouest. Une fois achevée en 1815, la tour fut en grande partie laissée à elleméme, ne servant plus qu’en temps de crise. Elle tint lieu de base de directions de tir au cours de la Seconde Guerre Mondiale. L’ouvrage intial est typique de tours martello angalises, fortifications côtières répandues dans les iles britanniques à l’époque napoléonienne.
