Each summer, as part of the Citadel's living history program, mid-Victorian Halifax is brought to life. The time period is 1869 when the 78th Highland Regiment was stationed at the Citadel. This regiment was one of the most famous Scottish units in the British Army and presented an impressive sight in their MacKenzie tartan kilts, feather bonnets and bright red doublets. As with any highland regiment, the heart and soul of the 78th was represented by its pipers. Dressed in contrasting green uniforms, they figured prominently in all aspects of a soldier's life. The 78th Highlanders developed a special, friendly relationship with the local citizens who lamented their departure in 1871.

Today, the Highlanders are portrayed by an historical re-enactment group comprised mainly of students. During the summer months, the 78th Highlanders perform precision foot and arms drills, sentry duty, bayonet exercises and firing demonstrations using original Snider-Enfield rifles.

No British fort would be complete without the Royal Artillery who were responsible for maintaining all ordnance, operating guns and manufacturing ammunition and powder. Today, re-enactors portraying the Royal Artillery can be seen about the fort performing their duties in blue uniforms featuring a red stripe down the pant leg and a pill box style forage cap. The Artillery perform drill, demonstrations on 12 pounder, 32 pounder smooth bores and 7" rifled muzzle loading guns. One of the most popular events at the Citadel is the daily firing of the noon gun.
