City of Pasadena Profile and Municipal Office Contact Information

Pasadena, located at the foot of the San Gabriel Mountains in northeast Los Angeles County, is a city renowned for its architectural grace, scientific innovation, and cultural sophistication. Incorporated in 1886 and long considered a crown jewel of the San Gabriel Valley, Pasadena blends Old World charm with cutting-edge intellect, offering residents and visitors a rich experience rooted in both tradition and progress.

The city’s most internationally recognized event is the annual Tournament of Roses, held every New Year’s Day since 1890. The Rose Parade, with its elaborate floral floats, equestrian units, and marching bands, draws millions of spectators and television viewers from around the world. Immediately following the parade, Rose Bowl Stadium, an iconic venue listed on the National Register of Historic Places, hosts the Rose Bowl Game, one of college football’s most prestigious matchups. The stadium also serves as a venue for major concerts, international soccer matches, and community events throughout the year.

Pasadena’s historic core is perhaps best exemplified by Old Pasadena, a revitalized 22-block district where 19th-century brick buildings house high-end retailers, boutique shops, artisan cafes, and fine dining establishments. This pedestrian-friendly area fuses historic preservation with modern urban energy, making it a premier destination for shopping and nightlife in the San Gabriel Valley.

Architecturally, Pasadena is a treasure trove. The city is a living museum of early 20th-century styles, particularly Craftsman and Arts and Crafts homes. The crown jewel of this tradition is the Gamble House, designed by Charles and Henry Greene in 1908, considered a masterpiece of American residential architecture. The city is also home to the Pasadena Civic Auditorium, an Art Deco venue that has hosted everything from Broadway shows to the Emmy Awards.

Pasadena is equally distinguished for its scientific and educational institutions. Foremost among them is the world-renowned California Institute of Technology (Caltech), a small but elite research university consistently ranked among the best globally in science and engineering. Closely affiliated with Caltech is NASA’s Jet Propulsion Laboratory (JPL), which has directed many of the United States’ most significant space exploration missions, including Mars rovers and deep-space probes. Both institutions contribute to the city’s international reputation for intellectual and technological leadership.

The city also boasts an exceptional cultural scene. The Norton Simon Museum, with its striking modernist design and tranquil sculpture garden, houses one of the finest collections of European art in the western United States, including works by Rembrandt, Degas, and Picasso. Nearby, the Pasadena Museum of California Art (PMCA) and USC Pacific Asia Museum celebrate both regional and global artistic traditions. The Pasadena Playhouse, designated the State Theater of California, is a historic performing arts venue known for its innovative productions and commitment to theatrical excellence.

Green space is integral to Pasadena’s character. The expansive Arroyo Seco, a seasonal riverbed that cuts through the western part of the city, is lined with parks, trails, and golf courses, including the historic Brookside Golf Club. The Huntington Library, Art Museum, and Botanical Gardens, located just south of the city in San Marino, is a cultural landmark whose vast research collections, world-class galleries, and themed gardens attract scholars and visitors alike.

Pasadena’s residential neighborhoods are known for their tree-lined streets, stately homes, and distinct character—from the elegant estates of San Rafael Hills and Linda Vista to the more eclectic, artistic communities of Bungalow Heaven and Madison Heights. Its schools, including those in the Pasadena Unified School District and private institutions like Polytechnic School and Westridge School, make it a desirable location for families.
