Which architectural feature inspired the original McDonald's Golden Arches?

The original McDonald's Golden Arches were inspired by the restaurant's distinctive yellow arches.

Architect Stanley Clark Meston designed the early McDonald's buildings with large yellow arches at the sides of the structure. The arches were visible from the road and helped the restaurants stand out in the roadside landscape of postwar America. Their bright color and curved shape made them useful as both architecture and advertising.

The arches were not initially created as the modern standalone letter M. They were physical elements of the restaurant buildings, often rising above the roofline. When viewed from certain angles, the paired arches formed a recognizable silhouette that later became one of the world's most famous corporate marks.

The Golden Arches are often described simply as McDonald's logo, but their history began in building design. The company progressively simplified and formalized the shape for signs, packaging, and advertising. This architectural origin is why the symbol has a distinctive connection to roadside restaurant design rather than being an arbitrary graphic.
