An apron in structure is primarily a raised section of ornamental stonework typically located beneath architectural features such as a window ledge, a stone tablet, or a monument.
Understanding the Apron
In architectural and structural contexts, the term "apron" refers to a specific component, often made of stone. Its function can vary slightly depending on the context, but it commonly serves both decorative and sometimes structural purposes.
Common Architectural Apron
- Definition: As noted in the reference, an apron is defined as a raised section of ornamental stonework below a window ledge, stone tablet, or monument.
- Appearance: It is often a prominent, shaped piece or panel that adds visual interest and detail to the facade of a building or structure.
- Purpose: While often ornamental, it can also provide a subtle transition between the feature above it (like a window) and the wall surface below, or help shed water away from the wall base.
Examples of Aprons
- Building Facades: A common place to see architectural aprons is beneath windows on the exterior of buildings. The reference specifically mentions that Burford Methodist Church has aprons beneath its five upper windows, serving as a clear example of this use case.
- Monuments and Tablets: Aprons can also be found below decorative tablets or monuments, providing a base or embellishment.
Aprons in Other Structural Contexts
The term "apron" can have different meanings in various engineering fields. The reference provides another significant historical example:
- Roman Bridges: Aprons were used by Roman engineers in the construction of Roman bridges. In this context, the main function of apron was to surround the feet of the piers. This structural use differs from the ornamental stonework beneath a window, highlighting that the specific function depends on the structure. This likely helped protect the base of the bridge piers from erosion or damage from water flow.
In summary, while the most commonly referenced structural "apron" in architecture is an ornamental stone feature beneath windows or tablets, the term can also apply to protective elements used around the base of structural supports in other engineering contexts, such as bridge piers.
| Context | Material (Common) | Location | Primary Function | Example |
|---|---|---|---|---|
| Architectural | Stonework | Below window ledge, tablet, monument | Ornamental, sometimes protective | Burford Methodist Church windows |
| Civil/Hydraulic | Varies (stone, etc.) | Around base of bridge piers | Protection (e.g., from erosion) | Aprons used in Roman bridges |
