Spanish Colonial fantasy, Brutalist concrete, modernist courtyards, and the architects who made San Diego look like no other city.
Last updated
San Diego's architecture is best understood as a series of layers. The Spanish Colonial Revival fantasy of Balboa Park was built for the 1915 Panama-California Exposition and became the city's visual signature. Irving Gill pioneered stripped-down modernism in La Jolla and Bankers Hill in the early 1900s. Louis Kahn's Salk Institute in La Jolla is considered one of the masterpieces of 20th-century architecture. Geisel Library at UC San Diego is the city's most photographed Brutalist building. Downtown mixes historic landmarks like the Santa Fe Depot and Hotel del Coronado with a late-20th-century skyscraper boom and a more recent wave of towers, libraries and ballparks. The best way to see it is to drive or walk three corridors: Balboa Park, the La Jolla / UCSD coast, and downtown's waterfront.
| Style | Where to see it | Key buildings |
|---|---|---|
| Spanish Colonial Revival | Balboa Park, Mission Hills, Old Town | California Tower, Museum of Man, Junipero Serra Museum |
| Early modernism / Irving Gill | La Jolla, Bankers Hill, Coronado | Watford House, Dodge House, Gill's service station |
| Brutalism | UC San Diego, Scripps Institution | Geisel Library, Galbraith Hall |
| High modernism | La Jolla | Salk Institute, Louis Kahn |
| Victorian / resort | Coronado, Gaslamp Quarter | Hotel del Coronado, Victorian-era commercial blocks |
| Contemporary | Downtown, East Village, Little Italy | Central Library, One America Plaza, Petco Park |
UC San Diego, La Jolla · William Pereira, 1970
The most photographed building in San Diego and one of the West Coast's great Brutalist statements. The library appears to float on concrete fingers, with glass boxes stacked above a canyon of eucalyptus. It was renamed for Audrey and Theodor Geisel in 1995 and now holds the Dr. Seuss Collection.
Local tip: Park in the Hopkins or Gilman structures and walk up Library Walk. The building faces west, so late afternoon light is best.
La Jolla · Louis Kahn, 1965
Widely considered one of the most important buildings of the 20th century. Two symmetrical wings of teak and concrete frame a travertine courtyard that draws the eye straight to the Pacific. It was commissioned by Jonas Salk, developer of the polio vaccine.
Local tip: Public tours are limited and must be reserved in advance; the courtyard view from the public entry is worth the effort.
Balboa Park · Bertram Goodhue, 1915
The ornate Spanish Colonial Revival buildings along El Prado were originally built as temporary exposition halls for the 1915 Panama-California Exposition. The fantasy proved so popular that the city rebuilt many of them in permanent materials.
Local tip: Start at the Cabrillo Bridge and walk east through the California Tower and the Museum of Man. The Botanical Building lily pond is the classic foreground.
Coronado · James Reid, 1888
One of the last surviving great Victorian beach resorts in the United States, with a red-tiled turret roof that dominates the Coronado beachfront. It was the largest resort hotel in the world when it opened.
Local tip: Walk through the lobby even if you're not staying — the woodwork and beach views are public-accessible.
Balboa Park · 1915, rebuilt 1935
The tower is the exclamation point of Balboa Park's skyline. The building's Spanish Baroque details, tile dome and carved figures were designed to look centuries older than they are.
Local tip: Tower tours are ticketed and sell out; book ahead if you want the view from the belfry.
Downtown, East Village · Rob Quigley, 2013
A nine-story steel-and-glass dome that changed downtown's architectural identity. The library includes a public roof garden, an auditorium, and a charter high school.
Local tip: Take the elevator to the top-floor reading room and roof garden for a free view of the bay and Coronado Bridge.
Downtown · 1915
Still an active Amtrak and commuter rail station, the depot is a Spanish Colonial Revival landmark with a grand waiting room, tile work and a 20-foot stained-glass window. It anchors the downtown waterfront edge.
Local tip: The waiting room is open to the public and one of the least visited beautiful interiors downtown.
Downtown · Helmut Jahn, 1991
San Diego's tallest building for decades, a sharply pointed postmodern tower that references the white passenger liners once common on the bay. It remains a defining element of the skyline.
Local tip: Best viewed from Coronado, the ferry landing, or Harbor Island at sunset.
La Jolla, Bankers Hill, Coronado · 1870–1936
The most important San Diego architect you've never heard of. Gill stripped away Victorian ornament before modernism had a name, using flat roofs, arched openings, concrete and white stucco. His Watford House, Dodge House and former La Jolla service station still stand.
La Jolla · Salk Institute, 1965
The Philadelphia architect left only a handful of buildings on the West Coast; the Salk Institute is the most significant. Its travertine courtyard, teak windows and precise light make it a pilgrimage site for architects.
UC San Diego, La Jolla · Geisel Library, 1970
The Los Angeles architect gave San Diego its most dramatic Brutalist landmark. Pereira also worked on the broader UC San Diego campus plan, which helped define the university's canyon-and-concrete identity.
Balboa Park · 1915 Exposition
Goodhue designed the core buildings of the Panama-California Exposition, importing Spanish Baroque, Plateresque and Churrigueresque details to create the fantasy city that became Balboa Park's permanent identity.
Central
The densest concentration of Spanish Colonial Revival in the country, plus the Botanical Building, the Old Globe, the Mingei Museum and the Museum of Photographic Arts in later buildings. Plan for a full morning.
Coastal
Gill houses in the village, the Salk Institute to the north, Geisel Library at UCSD, and the contemporary Scripps Institution buildings along the bluffs. A coastal architecture day trip.
Downtown-adjacent
A preserved mix of early-20th-century houses, including several Irving Gill designs, set on a hill with views toward the bay. Walk along First and Second Avenues.
Downtown
Victorian-era commercial blocks restored in the 1980s and 1990s. The architecture is smaller-scale than the modern towers around it and best seen on foot.
Island
The Hotel del Coronado is the headline, but the island has a full range of late-19th- and early-20th-century residential styles, from Victorian cottages to Craftsman bungalows.
Old Town
Adobe ruins, reconstructed mission-era buildings and the Junipero Serra Museum on Presidio Hill, designed by William Templeton Johnson in Spanish Revival style.
The Hotel del Coronado is the most widely recognized historic building, while Geisel Library at UC San Diego is the most photographed and architecturally distinctive modern building.
Spanish Colonial Revival, with heavy Spanish Baroque, Plateresque and Churrigueresque ornament. The buildings were designed by Bertram Goodhue for the 1915 Panama-California Exposition.
Yes, but public tours are limited and must be reserved in advance through the Salk Institute website. The courtyard view is the architectural highlight.
An early modernist architect who worked in San Diego and Southern California from the 1890s through the 1930s. He stripped away Victorian ornament and used white stucco, flat roofs and arched openings decades before modernism became mainstream.
Balboa Park's El Prado, Geisel Library's exterior, the Central Library's public roof garden, the Santa Fe Depot waiting room, and the Hotel del Coronado lobby are all free or mostly free to experience.
Point Loma and La Jolla have strong concentrations of postwar modernist houses. The Salk Institute is the high point of the era, and the San Diego Central Library represents a more recent contemporary take.
