Opus Quadratum is defined as what type of wall facing?

• A. Rectangular blocks with or without mortar joints
• B. Masonry with circular stones
• C. Intricate brick arches
• D. Column-supported stone veneer

Answer: (A)

Opus Quadratum involves facing a wall with large, rectangular cut stones laid in regular horizontal courses. The blocks have clean edges and are set so the joints line up vertically, often with little or no mortar showing. This creates a smooth, grid-like stone façade whose defining feature is the use of uniform rectangular blocks arranged in orderly layers. The other descriptions point to different techniques—circular stones would give a rounded, irregular look, brick arches describe curved brickwork rather than a flat block facing, and a stone veneer that's column-supported refers to a decorative layer attached in a different structural way.
