Old Pasadena: a historic-district preservation success story
The roughly 22-block stretch of Colorado Boulevard between Pasadena Avenue (west) and Arroyo Parkway (east) is known as Old Pasadena, and it's the densest concentration of pre-1940 commercial architecture in the San Gabriel Valley. The buildings here mostly date from the 1880s through the 1930s — brick and stone commercial structures in Spanish Colonial Revival, Mission Revival, Beaux-Arts, Art Deco, and Streamline Moderne styles that collectively document the boulevard's evolution from a 19th-century carriage road through the Route 66 commercial peak.
By the 1970s Old Pasadena had fallen into significant decline. Suburban shopping malls drew retail traffic away from downtown, the boulevard's vacancy rates climbed, and several historic buildings faced demolition threats. A community-led preservation effort beginning in the late 1970s — supported by the Pasadena Heritage organization, the city government, and private investors — gradually stabilized and restored the district through the 1980s and 1990s. The transformation is often cited as one of the most successful urban-historic-district revitalizations in the western United States, comparable in scope to similar efforts in Seattle's Pioneer Square or San Diego's Gaslamp Quarter.
Today Old Pasadena's commercial mix is substantially restaurants and retail, with several dozen restaurants spanning the full price range from casual to high-end, mid-tier and boutique retail, a small but active live-music scene, and a handful of bars and lounges that draw weekend crowds from across the San Gabriel Valley and eastern Los Angeles. The streetscape includes restored period streetlights, brick-paved alleys (notable: Mercantile Place and Champion Place), and decorative public art that reflects the district's pre-war commercial character.
