Make sure to visit the Citadel, a star-shaped fortress that overlooks the city. Take a guided tour to learn about its military history and explore the various exhibits and artifacts. Witness the changing of the guard ceremony, which takes place daily during the summer months. Enjoy the breathtaking views of the city and the St. Lawrence River from the Citadel's ramparts. If you're lucky, you might even catch a glimpse of the resident goats, the mascots of the Royal 22nd Regiment.
