Architectural Columns

A church building contains architectural elements that are common to all buildings; but also contains features making it identifiable as a church.

One aspect of a “church-identity” is verticality in which the height of the church building will make it stand out from other structures, and also bring to mind the idea of “the heavens above” with the uplifting architectural motion of church design. The columns of a church play a key role in “supporting” the verticality of the structure by enabling greater height and openness in the interior.

On your next visit to a church, try to identify the columns that are used and notice how they assist in developing a feeling of uplift in the building.

The Column
A column is a pillar, usually with a rounded or rectangular shaft, with a capital on top and a base on the bottom. The main purpose of the column is to provide support, although some columns are present for decorative purposes. The columns support the entablature which is a horizontal beam between the columns supporting the overhead structure of a building. Columns were (and are) especially important for large structures in the absence of supporting arches; although, in some cases, they support arches themselves.

The three fundamental parts of a column are:

Shaft: A vertical pillar which may be circular, rectangular or polygonal. They are either uniform in diameter or taper toward the top or bottom. Many are fluted, i.e. have vertical grooves running from top to bottom which aid in making a column appear more perfectly round. A supporting column is attached to a capital on the top and base on the bottom. A rectangular decorative column that is attached to a wall is known as a pilaster.

Capital: The top part of the column that distributes the load of the building in a horizontal fashion from a column across the entablature (horizontal support/beam above) to adjacent columns. Capitals range from simple square blocks to highly decorated inverted bells. The form of the capital is the part of the column that most readily distinguishes the Architectural Order of the building (see below).

Base: The bottom part of the column supporting the load of the building. The rounded or rectangular base is larger in diameter than the shaft above to distribute the building weight over a larger area. Note: some types of classical columns (Doric) do not have a base, but rest directly on the pavement underneath a row of columns.
