Citadel Hill (Fort George)
The first major permanent fortification appeared on Citadel Hill in the American Revolution. The possibility of attack during the Revolution required a larger fortification to protect the city from an American or French attack. Built in 1776, the new fort on Citadel Hill was composed of multiple lines of overlapping earthen redans backing a large outer palisade wall. At the center was a three-story octagonal blockhouse mounting a fourteen-gun battery and accommodating 100 troops. These works required that the hill be cut down by 40 feet. The entire fortress mounted 72 guns. Citadel Hill and the associated harbour defence fortifications afforded the Royal Navy the most secure and strategic base in eastern North America from its Halifax Dockyard commanding the Great Circle Route to western Europe and gave Halifax the nickname "Warden of The North".
