Coign

A coign (also spelled 'coin' or 'quoin') refers to an external angle of a wall or building. Specifically, it's where two walls intersect, forming a corner. It's often emphasized by the use of dressed stones, bricks, or other building materials that project outward. These projecting stones, or quoins, can add strength, visual appeal, and structural definition to the corner of a building. The term can also loosely refer to the specific projecting stones themselves, particularly when they are decorative.

Coign meaning with examples

• The architect highlighted the building's coigns with contrasting granite blocks, creating a strong visual border. The careful placement of each stone at the coign added considerable structural support, too, ensuring the building's corner's resilience against weathering and stress. These were chosen for both practical and decorative purposes, adding a unique character to the otherwise bland facade.
• During the renovation, the coigns of the old manor house required careful repointing to preserve their integrity. Each coign was examined thoroughly to ensure no structural weakening existed. Replacing decayed bricks that formed the coigns ensured that the wall's corners would continue to stand sturdy, adding longevity to the building. This highlighted the importance of preserving traditional architectural elements.
• The artist focused his painting on the play of light and shadow across the coigns of the ancient castle. He wanted to emphasize the texture that the exposed stones in the coign created. This angle showed the coigns, where the stonework of the castle walls met, creating a visual anchor. It highlighted the weathered texture of the centuries-old material.
• The castle's defense relied on the strength of its coigns and the strategic placement of arrow slits. These coigns strengthened the walls and provided clear fields of fire for the archers within. Enemies had no chance to get into the castle without being met at the coigns. The coigns therefore acted as a crucial part of the defensive architecture.
