Within the citadel, architectural structures such as guard towers, storerooms, and barracks for the sentinels are thoughtfully arranged. These spaces serve not only military purposes but also stand as poignant reminders of many historical memories. The remnants of battles and the resistance against French colonial forces in the early 20th century have left an indelible mark on the hearts of the people of Da Nang.
