The 1918 stagecoach stop and the Route 66 transition
The Golden Spur's original 1918 building served as a stagecoach stop on the regional stage routes connecting Glendora and the surrounding foothill communities to Pasadena, Los Angeles, and the Inland Empire towns. The stagecoach era in Southern California was already in its final years by 1918 — automobile travel was rapidly replacing horse-drawn transportation across the region — but stage routes continued to serve some rural and connecting routes through the 1920s, and a building with a good location along a major regional corridor made sense as a small eating-and-rest stop for stage passengers and the early automobile travelers who were beginning to dominate the same roads.
The transition from stagecoach stop to roadside diner happened gradually across the 1920s. When U.S. Route 66 was officially designated in 1926, the highway followed essentially the same alignment that the stage routes had used for decades — the path through Glendora was already an established travel corridor, and Route 66's national designation simply formalized and elevated what had already been a busy regional road. The Golden Spur's building had already been informally serving travelers and was well-positioned to become a designated Route 66 stop.
The Western-themed decor that defines the current Golden Spur — wagon wheels, brass spurs (the source of the restaurant's name), saddle and bridle displays, wood paneling, lantern-style lighting, vintage photographs of Glendora and Southern California from the 1900s through 1950s — was developed during the 1930s and 1940s as the restaurant grew into its full Route 66 diner identity. Subsequent ownership across the decades has preserved rather than modernized the aesthetic, which is the reason the interior reads today as a genuine vintage Western-themed diner rather than a reconstructed retro concept.
