Which McDonald's building feature inspired the two-arch logo that became the Golden Arches?

The McDonald's two-arch logo was inspired by the restaurant's roadside arches.

Architect Stanley Meston designed large yellow arches as part of the McDonald's restaurant in San Bernardino, California, in 1953. The structures were intended to make the building visible to passing motorists and give the restaurant a memorable silhouette.

The arches were architectural features before they became a corporate logo. In the 1960s, McDonald's adapted the two forms into a stylized M, creating the Golden Arches symbol recognized around the world.

This history explains a common mix-up: the logo did not begin as an abstract letter designed independently of the restaurants. It grew from a practical roadside design, then became one of the most influential examples of architecture becoming brand identity.
