It rained that day in Edinburgh, and the weather was colder, as it was in the Scottish Highlands, but it did not weaken our visit to Edinburgh at all. The castle is very British, and its location is very good. It has to be said that the British people have a good set of ways to protect historical sites. It is especially recommended that big forts, very special, and every wall cave is a scenic line to look out. The street outside the castle must be visited. The street performance art in Britain is really good and interesting. Every palace in the castle has its own characteristics. What is interesting is that their explanation is not a rigid introduction by the lecturer, but a live performance.
