A church-like building at the west end is the famous Scottish Whisky Heritage Center. It can go for free drinks. St. Gills Cathedral, which is shaped like the Crown of Scotland, is also on the side of the street. There are famous political economists on the square. Famous Principle" The theory of the invisible hand "Adam Smith's statue, the theory of the invisible hand" means that supply and demand are automatically balanced and prices are automatically adjusted according to the invisible hand of supply and demand, rather than changing at will! How profound! Many Scots will hold weddings here, and sometimes street artists in Scottish skirts play bagpipes in the square, and the sound is very loud. It sounds wonderful and reminds visitors to stay in Scotland's ancient centre from time to time. On Royal Mile Avenue, you can sit in a bar or choose Scottish local gifts.
