Why Do Old Brick Buildings Often Use Corner Stones: Functional vs. Aesthetic

The corners of old brick buildings are often adorned with corner stones, a practice that serves both functional and aesthetic purposes. Understanding the reasoning behind this tradition can provide valuable insights into historical architecture and design principles.

Functional Purpose

The use of corner stones in brick buildings is not merely a decorative element. It is a carefully considered design choice that addresses several important functional requirements:

Structural Support

Stone is typically much stronger than brick, and this strength is crucial at the corners of buildings. The corners are critical stress points, and the use of stone enhances the overall structural integrity. Stones help to distribute the weight more evenly, reducing the risk of cracking and ensuring the longevity of the structure.

Durability

Stone is significantly more resistant to weathering and erosion compared to brick. By reinforcing the corners with stone, builders ensure that these vulnerable areas can withstand the elements over time. This durability is essential in ensuring that the building remains stable and intact for decades or even centuries.

Foundation Stability

In some cases, corner stones help to anchor the building to its foundation, providing stability against settling or shifting. This additional support is crucial for maintaining the structural integrity of the building over the long term.

Aesthetic Feature

Beyond the functional benefits, the inclusion of corner stones also serves an aesthetic purpose:

Aesthetic Appeal

The contrast between the brick and stone can create a visually appealing look. This technique can highlight the building’s corners, adding character and interest to the overall design. The juxtaposition of these materials can significantly enhance the beauty and charm of the structure.

Historical Tradition

Many architectural styles incorporate stone at the corners as a traditional design element. This practice can be seen in various historical buildings, reflecting the craftsmanship and design philosophies of the time. The inclusion of corner stones is a testament to the architectural traditions and the ingenuity of past builders.

For example, corner stones are often inscribed with the date of the foundation laying, representing the first blocks set into place. These corner stones, also known as 'quoins', are a decorative feature that impart strength, particularly in stone buildings where rubble is used as the main walling. However, in brickwork, they serve no purpose apart from decoration.

While the use of stones at the corners of brick buildings serves a vital structural function, it also contributes to the aesthetic quality of the architecture. This blend of functionality and beauty has made corner stones an enduring and treasured part of architectural history.
