What architectural symbol became McDonald's best-known logo element?

The architectural symbol that became McDonald's best-known logo element is the Golden Arches.

The arches began as physical features of McDonald's restaurants rather than as an abstract corporate mark. Architect Stanley Clark Meston designed the early California restaurants with large yellow arches on either side of the building. The structures helped make the restaurants visible to passing motorists.

In 1962, designer Jim Schindler combined the two arches into the stylized “M” associated with McDonald's. This transformed an architectural feature into a portable brand symbol that could appear on signs, packaging, advertisements, and later digital media.

The arches are often described simply as the McDonald's “M,” but their history explains why the company uses a distinctive curved form instead of an ordinary letter. They also belong to the broader visual culture of postwar American roadside architecture, when restaurants competed for attention from drivers.
