Miles Mountain Fort (Mills Mount Battery), there is a famous big dragon, it has a very practical name: 1 o'clock big dragon (One o'clock gun). This 1 o'clock cannon is used for sailors moored on the ship in Forth Bay (Firth of Forth), and fires on time at 1 o'clock every afternoon. Although people no longer need to be right against the gunfire, it still maintains tradition, except for a few holiday breaks, and can still hear its guns at 1pm every day. When we arrived, we were already a crowd of people watching. We saw the pomp of guns at 1 o'clock from afar. Finally, we were fortunate to take a photo. We left here with satisfaction. Now it has become a tourist resort for friends from all over the world. The tourists are like a lively let, Edinburgh is guarded by Edinburgh Castle day and night. Not lonely anymore.
