Baseboard
Baseboard hides the gap between the wall and floor and for that reason it is present in almost every room of the house. It was developed in the eighteenth century as owners of grand houses began to prefer plaster walls over wood paneling, and today it remains true to its purpose of protecting wall surfaces from shoes, furniture, and other domestic hazards. As an architectural detail, baseboard provides a foundation to a wall, as a base does to a column, giving the eye a starting point as it absorbs a room's decoration.
