I work at the Halifax Citadel, and have for three years now. It’s Halifax’s best attraction, by far and if you’re visiting the city I would make sure to check it out at least at noon for the firing of the cannon (which happens year round) and the noon day concert (which only happens during the summer, when the entire Citadel is open). Also, the coffee shop has home made soups and sandwiches that are worth checking out. The cook is a wonderful lady!
