On the hill of castles in the famous port city of caliphax in canada, a condescending octagonal star fortress is the fourth fortress built here in 1825 and one of the largest stone-built military fortresses in north america. Now, at noon every day, the octagonal star fortress is holding a salute, which makes tourists feel both nervous and exciting. Of course, it is pleasing to enjoy the bagpipes played by the Legion soldiers and the neat drills and marching.
