A group of people, likely pilgrims, is walking in a city square on a sunny day. Many of them are wearing blue vests with "B2" printed on them. The people are diverse in age and clothing styles, including traditional robes and casual wear. They seem to be moving as a group, possibly guided by someone. The square is paved with grey stones, and tall buildings surround it. The architecture is modern with some traditional elements. The overall impression is of a organized group of pilgrims exploring a city.
