Which architectural feature inspired McDonald’s Golden Arches branding before it became a letter M?

Restaurant roof arches inspired McDonald’s Golden Arches branding before the symbol became a letter M.

The early McDonald’s restaurants used large yellow arches as architectural features at the front or sides of the building. They were intended to attract passing motorists and make the roadside restaurant easy to recognize.

Architect Stanley Clark Meston designed the best-known early arch structures for McDonald’s in the 1950s. The arches later influenced the corporate logo, which combined two arches into a stylized M. This is why the modern symbol is called the Golden Arches even when it is printed without a building.

A common mix-up is to assume that the logo came first and the buildings copied it. Historically, the relationship ran in the other direction: the restaurant architecture supplied the visual idea, and later graphic design turned it into a compact corporate mark.
