The Great Wall of China entrance building
The Great Wall of China is a fascinating place with what seems like an endless number of stairs, walls, fortified positions, and entrances. This stock photograph clearly shows a small fortified station building and winding stairs leading down to bunkers or structures on the wall. This section of the Great Wall of China is made of stone and brick. This building on the Great Wall of China was the entrance closest to Beijing, where tourists could access it. You can see the sign on the right-hand side.
