What is a Cornice?
A cornice is decorative trim located at the meeting point between walls and a roof or ceiling. Cornices are used on building exteriors and interiors. On the outside of structures, a cornice is located where the wall meets the roof. When you look up, it’s the horizontal area that sticks out at the top of the wall, right below the roofline. Think of it like a crown. In room interiors, the cornice is the decorative wood or plaster molding, a surface with raised designs (sometimes made of plaster, hence the name molding) that circles a room right below the ceiling
