What is a dome?

What is a dome?

• A. A pointed arch in Gothic architecture.
• B. A rounded vault forming the roof of a building.
• C. A type of temple column.
• D. A decorative frieze on a wall.

Answer: (B)

A dome is a rounded vault that makes up the roof of a building. It usually sits over a circular or polygonal plan and creates a spacious, curved ceiling inside. Structurally, a dome is formed by arches joined into a continuous curved surface, distributing weight outward and downward to the supporting walls or piers. This is what gives large interior spaces a soaring, monumental feel. This shape is different from a pointed arch, which is a Gothic feature that directs weight differently; it isn’t a roof shape itself. It’s also not a temple column, which is a vertical support, nor a decorative frieze, which is a horizontal band of sculpture on a wall.
