What is architectural pilaster?

An architectural pilaster is a decorative feature that resembles a flat column or upright rectangle on the exterior surface of a building. The pilaster is usually made out of stone, wood, or plaster and is attached to the façade of the building.

Pilasters are typically used to add depth and visual interest to a building's façade. They can be plain or ornate, with decorative motifs such as Corinthian or Ionic capitals. Pilasters may also be adorned with sculptures, carvings, or other decorative elements.

In classical architecture, pilasters are often used to create a rhythm of vertical elements, helping to visually organize a building's facade. They can be used to create a sense of order and symmetry, and to emphasize the importance of certain architectural features such as windows or doors.

Pilasters are often associated with neoclassical architecture, which drew heavily on classical forms and motifs. However, they can be found in a variety of architectural styles, from Gothic to Art Deco.
