A cornice is a decorative architectural element that projects horizontally from the top of a wall, building, or furniture piece. It serves both functional and aesthetic purposes, primarily redirecting rainwater away from building walls and visually capping a structure. 🏛️ Historical Origins
Ancient Greece: Originated as the topmost element of the classical entablature.
Classical Orders: Crowned the pediment in Doric, Ionic, and Corinthian styles.
Evolution: Transitioned from stone structural supports to decorative plaster and wood elements. 📐 Structural Components
Corona: The wide, flat vertical face that creates the main projection.
Cymatium: The topmost molding, often shaped like an “S” curve.
Bed Molding: The lower moldings supporting the main projection. 🏠 Main Architectural Types
Exterior Cornice: Caps the outside walls of buildings to shed rainwater.
Interior (Crown) Molding: Conceals the structural joint where walls meet ceilings.
Box Cornice: Encloses the rafters of a roof for a clean finish.
Architrave Cornice: Placed directly above doors or windows as an ornamental header. 🛠️ Common Materials
