It is a mile-long street known as the Royal Mile, from Edinburgh Castle to Holyrood Palace, and is known as "one of the most attractive streets in the world" with many royal buildings on both sides of the street, magnificent, and the busiest tourist street in Edinburgh's Old Town. Only Princes Street in Edinburgh's new city can match it. During the annual Edinburgh Festival, the High Street becomes the central focus of the city, crowded with tourists and street artists, and a church-like building at the west end is the famous Scotch Whisky Heritage Centre, where you can go in for a few free drinks. St. Giles Cathedral, which is shaped like the crown of Scotland, is also on the street. There are famous political economists in the square. They once proposed the famous principle of "the theory of the invisible hand" Adam Smith statue. This "the theory of the invisible hand" means that supply and demand are automatically balanced. Prices will be automatically adjusted according to the invisible hand of supply and demand, and will not change at will by human will! How profound! Many Socrates will hold weddings here, and sometimes there are street performers in Scottish dresses playing bagpipes in the square, which sounds wonderful. Visitors are reminded to be in the ancient center of Scotland. On the Royal Mile Road, you can sit in the bar or choose Scotland's local products.
