What is a cornice in the context of architecture?

A cornice in the context of architecture refers to a horizontal decorative trim that is typically found at the top of a building or structure. It serves both aesthetic and functional purposes, often enhancing the visual appeal of a facade by adding detail and character. Cornices can be made of various materials, including wood, plaster, or stone, and are frequently used to define the transition between the wall and the roof line, creating a visually pleasing outline. They may also help direct water away from the building, reducing the risk of water damage.

This understanding of cornices is essential for professionals in the field, as it plays a significant role in architectural design, contributing to both the style and functionality of a structure. In contrast, the other options pertain to different aspects of construction or materials, which do not relate directly to the decorative architectural element defined as a cornice.
