Definition:
The “Greek Cross” is a type of cross with four arms of equal length, intersecting at right angles.
Etymology:
The term “Greek Cross” originates from its prominent use in the art and architecture of the Greek-speaking Eastern Orthodox Church. The word “cross” derives from the Latin “crux,” which originally meant a wooden instrument of execution but later came to symbolize the Christian faith. The “Greek” descriptor reflects its association with Byzantine and Eastern Christian traditions.
Description:
The Greek Cross (✚) is a cross with four arms of equal length, creating a perfectly balanced shape. Unlike the Latin Cross, which has a longer vertical arm, the Greek Cross is symmetrical in all directions. This shape has been widely used throughout history, appearing in ancient art, architecture, and religious symbolism.

Symbolism:
The Greek Cross was a common design in Byzantine churches, seen in mosaics, floor plans, and iconography. The cross’s balanced form gave it a sense of harmony and stability, which may be why it was later adopted as the plus symbol in mathematics. The connection between the two isn’t just a coincidence—symbols are often chosen for their meaning, and the Greek Cross already carried an association with order and structure.
The interior layout of a Greek Orthodox church is often designed in the shape of the Greek Cross, with four arms of equal length extending from a central point. The lower arm corresponds to the entrance, where rows of pews are arranged on either side of a central aisle. As one moves forward, open spaces often flank the front pews, leading to the altar at the head of the church—the symbolic top of the cross. At the very center, where the arms intersect, a prominent feature such as a dome or decorative element is typically placed. This central space is frequently marked with a Greek Cross, emphasizing the architectural and spiritual vision of the church.
