Definition

Structural Element

In architecture, a pilaster serves as a load-bearing architectural element. It is characterized by a thickened section of wall or a column that is integrated directly into the wall structure. This design allows it to carry structural loads, contributing to the overall stability of the building.

Decorative Feature

Beyond its structural capacity, the pilaster is also a prominent decorative element, particularly in classical architecture. It is designed to give the visual impression of a supporting column, articulating and enhancing the surface of a wall. As an ornament, it presents a flattened profile, often retaining the visual characteristics of a column without its full three-dimensional form.

Distinction from Columns

While resembling a column, a pilaster is fundamentally integrated into the wall. Unlike an engaged column or a buttress, which can project significantly and bear substantial structural loads independently, a pilaster's primary role can be aesthetic, enhancing the wall's visual rhythm and classical proportions. Its flattened nature distinguishes it from a fully projecting column.

Classical Architecture

Alberti and Wittkower

Architectural historian Rudolf Wittkower noted that Leon Battista Alberti reintroduced the pilaster into wall architecture, describing it as "the logical transformation of the column for the decoration of a wall." This highlights the pilaster's role in adapting classical column forms for surface articulation.

Components and Proportions

In classical contexts, a pilaster typically features a capital at the top and a plinth or base at the bottom, mirroring the components of a column. It often adheres to the proportions of a specific architectural order (e.g., Doric, Ionic, Corinthian). However, unlike a true column, a pilaster usually lacks entasis (the slight outward curve in the shaft).

Architectural Applications

Pilasters are frequently employed to frame openings such as doorways and windows, providing visual emphasis. They can also be used in conjunction with columns, appearing set back from freestanding columns that support overhead structures like porticos. Additionally, pilasters can support recessed elements like archivolts or serve as a base for decorative brackets.

The Canton

Corner Element

When a pilaster is positioned at the intersection of two walls, specifically at a corner, it is referred to as a canton. This architectural term denotes a pilaster that integrates into the corner structure, providing both visual definition and potential structural reinforcement at this critical junction.

Styles and Evolution

Renaissance and Baroque

During the Renaissance and Baroque periods, architects extensively utilized pilasters, often adapting them with varied forms and ornamentation. They were employed to create visual continuity across multiple stories, particularly in the concept of the "giant order," where pilasters span two or more levels.

Historical Adoption

The use of pilasters, drawing inspiration from ancient Greek and Roman architecture, saw a resurgence during the Italian Renaissance. This trend continued through subsequent architectural movements, including the Greek Revival, and remains a feature in various forms of modern architecture, demonstrating its enduring aesthetic appeal.

Surface Treatment

Similar to columns, pilasters can feature plain or fluted surfaces, reflecting different architectural styles and preferences. The decorative treatment of the pilaster's shaft and capital allows for significant stylistic variation, adapting classical principles to diverse design contexts.
