Spur (architecture)

In architecture, a spur refers to a projecting feature that reinforces or protects a wall or other structure. It can take on several forms and serve various purposes:

• Buttress Spur: A type of buttress that projects from a wall, providing additional support against lateral forces. It's similar to a standard buttress but may be smaller or more decorative. Spurs often appear as smaller, less pronounced versions of buttresses, blending more seamlessly into the wall's design.

• Corner Spur: A strengthening element at the corner of a building, designed to prevent the corner from being damaged by impact or wear. This can be a simple chamfered edge or a more substantial projection. Corner spurs are particularly common in areas prone to pedestrian traffic or vehicle impact.

• Coastal Defence Spur: A structure built to protect a coastline from erosion or wave action. These spurs often extend seaward and are designed to dissipate wave energy. This type of spur is often constructed of concrete or large stones.

• Decorative Spur: A purely ornamental projection, often found on gates, parapets, or other architectural features. While it may provide some minimal structural benefit, its primary purpose is aesthetic enhancement.

The specific design and function of a spur are dictated by the building's structural needs, the materials used, and the overall architectural style.
