Arriving at Edinburgh Castle, a large number of tourists flocked to this must-see attraction in Edinburgh, and a crooked serpentine line formed at the gate of the ticket office. We didn't waste much time because we used Scottish passes to follow the team into the scenic spot. After entering the castle, he paid cash to rent a guide with Chinese explanations, which was 3.5 pounds for adults and 2.5 pounds for people over 60. Many tourist attractions in Britain offer similar discounts for people over 60 years of age with tickets. Put on the guide and start the tour in the order of scenic spots, listening to the detailed explanation and looking at the scenery. Edinburgh Castle is situated on the high ground and is a good place to overlook the whole city of Edinburgh. This castle, which dates back to the 6th century A.D., stands on an extinct volcano in the center of the city. It once existed as a royal residence, military fortress and prison. It is a testimony of Scottish history and is now included in the World Heritage Site. During our tour, we can enjoy the city scenery of the Scottish capital from different angles. The whole city is dominated by black, with tall buildings, towering bell towers, distant sea and streets beneath our feet, which are pleasing in both breadth and depth. Edinburgh Castle covers a large area and deserves the title of the first castle in Scotland. When you enter the castle, besides the crowded crowd, the rich exhibits in the room are impressive. In the process of listening to the commentary, we queued up to visit the Lights of Scotland, where crowns, sceptres and swords made visitors queue for half an hour to see its true face. We are no exception to waiting in line, and photography is strictly prohibited after entering the indoor exhibition hall. There is also a huge "Stone of Fate" in this exhibition hall, which is necessary for the King of Scotland to take office, and this stone has a story of wandering and bumping. In Edinburgh Castle there is also an obscure chapel, which is called St. Margaret's Chapel, but it is the oldest building in Scotland. There are also the National War Memorial, the Cavalry Guard Museum, the Scottish Legion Museum and the War Museum in Edinburgh Castle. Because of the relationship between time and time, we all went inside to have a look at the flowers. It was almost 13 o'clock when we finished the tour and stepped out of the castle. Unexpectedly, at this moment, the whole castle square is crowded, people are looking in one direction, while many people hold up their cameras, as if waiting for an upcoming moment. Suddenly we thought of the old tradition of hearing that at 13:00 a.m. every day, a gun fired at the Edinburgh Castle to announce the time. So quickly look for a place to watch, not yet standing firm suddenly a huge gunfire, so that quiet tourists then began to noise, followed by people began to disperse. For a time, the Castle Square was as lively as a meeting to dissolve, and we walked out of the castle with the crowd.
