The architecture in this lesson is dated in the range of the third century AD to fourth century AD in Rome.
Below is a timeline highlighting the period covered in this lesson.
Like art, early churches are a reflection of the cultures in which they were created. Early Christians didn’t necessarily have an inherent artistic style, so they drew upon what they knew or what they had been exposed to.
Churches are often re-purposed buildings or temples. Two main design plans for churches were used in the period explored in this lesson: the basilica design and the central plan. The basilica design was essentially an elongated rectangle that formed the central nave, terminating in an apse. The apse area with a triumphal arch, which originally would have been where the emperor was seated, instead became an area for the Christian altar, clergy seating, and, in many cases, the choir as well.
Here is a diagram of the basilica design:
Here is a different example of the basilica style, this time with a transept, which is the crosspiece that was added to give it more of a cross shape.
A centrally planned church has no long central nave. Instead, the altar is positioned in the middle of the church, and is surrounded by a circular walkway called an ambulatory. This style of church became more popular in the fourth and fifth centuries, but was largely replaced by the basilica-style design later on. The cross shape, which originally was more of a coincidence, eventually became its own major and intentional design element in the planning of churches.
Below is a diagram of a centrally planned church. Notice the altar in the center and the surrounding walkway.
Many early churches were based on the design of the Roman basilica, which lent itself well to Christian religious ceremonies. Originally used as meeting or audience halls, the basilica was a rectangular shape with a long central aisle called a nave, that terminated in a rounded, semi-circular section called an apse.
Not all churches were based on this basilica design, however. It was common to reclaim a temple or building to be repurposed as a church, and this was the case with Santa Costanza in Rome. Santa Costanza was originally built as a mausoleum for the Emperor Constantine’s daughter, but later was converted to a church. Because of its original purpose, Santa Costanza is based on what’s called a central plan.
Below is an interior view of Santa Costanza, which was originally constructed in 350 BC (required image).
This image is taken from the ambulatory, which is separated from the central area and altar by a colonnade of Corinthian-style columns. A clerestory provides light from above. Notice the windows.
The next image is of one of the surviving mosaics from inside Santa Constanza (required image).
The basilica style can be seen in several other churches, including Old Saint Peter’s Basilica in Rome, diagrammed below (required image).
The term “old” is to distinguish it from the newer Saint Peter’s, built centuries later. If you look closely, you can see the rectangular basilica design with its central nave and auxiliary aisles, the cross shape, and the apse. It was originally constructed in 360 AD.
Nothing from Old Saint Peter’s Basilica survives. It was deconstructed and a new church, the new St. Peter’s Basilica, was built in its place. However, this fresco of Old Saint Peter’s provides a nice cross-section of what the fourth-century building looked like (required image):
Notice the colonnade and rounded arcade, which is that row of arches, as well as the tiered roof and resulting clerestory at the very top. In many ways, the basilica of Old Saint Peter’s evokes many of the design elements of Egyptian temples from centuries earlier. It’s no wonder, though, given that the Romans themselves were inspired by the stylistic conventions of ancient Egypt.
This image is of the basilica-style fifth-century church of Santa Sabina in Rome (required image):
At first glance it could be mistaken for the basilica at Trier, Germany, which has a very similar design, as well as an exterior brick construction. However, the interior features very familiar design elements. The central nave and side aisles are separated by a Corinthian-style colonnade that you can see here (required image):
Note the rounded arcade that supports the structure, with the clerestory above.

The walkway between the sections of seats located, for example in a theater.
An area for walking, usually semicircular, around the apse of a church.
An architectural term; a recess or semicircular space in a building, vaulted and used often by the choir in a church.
A columned meeting hall in ancient Rome, later a church with columns.
The main church that contains the bishop’s throne.
A part of a building that rises above the roofs – basically windows above eye level primarily for allowing light and ventilation.
A tomb or building containing tombs.
A system of patterns on a floor, wall, ceiling constructed of small color pieces of inlaid stone, glass, or clay or other types of materials.
A long central aisle that extends the whole length of the church.
