The history of the Berlin Wall is very interesting.

He hung a picture on the west wall.

He hung a picture on the eastern wall.

He hung a picture on the northern wall.

He likes climbing rock faces.

I really liked the color and design of this dress.

The red color in this picture was made with red iron oxide.
