The main street in front of Buckingham Palace is greened on both sides and the whole street is spacious. Although there seems to be a lane, there is hardly any car in sight, but there is a neat line of guards. You can see the horse-riding army. The pedestrian street is often the only way for the Queen's patrol. The whole road is also a good angle for many people to take photos. I like the huge green land on the south side of the road. The special environment is also equipped with artificial lakes and so on.
