Visit Edinburgh Castle. The castle was the royal castle of Scotland from the 12th to 16th centuries A.D. and became a military base in the 17th century. It belongs to the Historic Scotland and still has troops stationed on the castle. Most of the castle's buildings were destroyed in the long siege of the 16th century, but a few survived the siege. The most famous one is the St. Margaret's Chapel (Figure 8), which was built in the early 12th century. This church is the earliest preserved building in the region and still stands there. Castle is one of Scotland's most popular tourist attractions, and it can meet more than 1.2 million visitors from all over the world every year. Please note: If you don't want to queue up to buy tickets (Figure 4), please book your tickets online in advance (Figure 5). Voice guides are paid extra (Fig. 6) in Chinese, but thousands of tourists come here every day, and they will soon be sold out. English tour guides start on time. The gathering place is next to the voice guide (Figure 7). A red timetable shows the starting time of the next tour guide. There are Chinese picture albums for 5 (fig. 9) and 4 for tickets at the same time. After visiting the castle, it was not as good as I had imagined, because there were so many visitors and people everywhere, which made people feel irritable. The Castle feels shocked in the distance. In addition to the appearance of the building, the choice of the objects to see is not as shocking as the building.
