"picture rail"的定义和意义

What is a "picture rail"?

A picture rail is a horizontal molding or trim installed along the upper part of a wall, typically near the ceiling, used to hang pictures or artwork. It provides a way to display artwork without putting holes in the wall, as wires or hooks are attached to the rail rather than directly to the wall. Picture rails are often found in older homes but are still used today for their practical and decorative purposes. They help keep walls intact and allow for easy rearranging of artwork.
