The Story of
Orange County
From the Tongva and Acjachemen homeland and Mission San Juan Capistrano, through the rancho era, the citrus and oil booms, the 1889 county split, and Disneyland — the layered history of the place where Southern California learned to dream.
A Region Built in Layers
Orange County's history stretches back more than 10,000 years to the Tongva (Gabrieleño) and Acjachemen (Juaneño) peoples, who lived — and still live — across the coastal plains, river valleys, and canyons of what is now OC. In 1769, the Portolá expedition became the first documented European journey through the region, and in 1776, Father Junípero Serra dedicated Mission San Juan Capistrano — the seventh of California's 21 Spanish missions.
From the great Mexican ranchos of Santiago de Santa Ana and Mission Viejo, through the 1889 county separation that made Santa Ana the seat, to the Sunkist citrus empire, the oil booms of Huntington Beach and Brea, the opening of Disneyland in 1955, the postwar suburban explosion, and the rise of Irvine as a master-planned edge city — Orange County has continuously reinvented itself while keeping every previous layer in view. This is the story of how a rural mission and rancho region became one of the great coastal counties of the Pacific.
Orange County wasn't actually named for orange groves — Valencia orange production exploded after the county was founded in 1889, but the name was chosen because it sounded sunny and welcoming to settlers.

Mission San Juan Capistrano Founded
Father Junípero Serra dedicates Mission San Juan Capistrano — the seventh of California's 21 missions and the only one personally founded twice by Serra.

Mexican Independence & the Rancho Era
After Mexican independence and the secularization of the missions, vast cattle ranchos cover what is now Orange County.

Mexican Cession & California Statehood

Founding of Anaheim, Santa Ana, Tustin & Orange
A wave of pioneer towns is founded across the future Orange County — including a German wine colony at Anaheim and the agricultural settlements that would become its civic core.

Orange County Splits from Los Angeles County
After years of campaigning, the southern townships of Los Angeles County vote to form their own county — and Santa Ana is chosen as the county seat.

The Citrus Empire — How OC Got Its Name
Orange and lemon groves cover hundreds of square miles of the county — and the iconic Sunkist brand is born here.

A Coastal, Multicultural OC of 3.2 Million
Modern Orange County is a coastal, multicultural region of 3.2 million people, 34 cities, 42 miles of coastline, and a uniquely layered cultural identity.
Why This History Matters Today
You can read Orange County's history just by walking through it. The bell wall at Mission San Juan Capistrano still rings. The 1871 plaza in Old Towne Orange still anchors a working downtown. The 1901 Old Courthouse still stands at the center of Santa Ana. The Sears-kit farmhouse where Richard Nixon was born still sits in Yorba Linda. The 1919 Sunkist Packing House is again drawing crowds. And Disneyland — 70 years later — is still the economic and cultural heart of Anaheim.
That layered, visible past is what makes OC unusual among American suburban regions — a place where every era is still present in the streets. Understanding it is what turns a visit into a connection, and a move into a sense of belonging.
Historic Landmarks
Visit the places where Orange County's history was made — from Mission San Juan Capistrano to the 1901 Old County Courthouse to the original 1919 Sunkist Packing House.

Mission San Juan Capistrano
The 'Jewel of the California Missions' includes the dramatic ruins of the 1806 Great Stone Church, the 1782 Serra Chapel (the oldest building in continuous use in California), period gardens, and the famous returning cliff swallows. A National Historic Landmark and the cultural and historic anchor of South Orange County.

Old Orange County Courthouse
Completed in 1901 and built of red Arizona sandstone in a Romanesque Revival style, the Old Orange County Courthouse housed the county's courts and government for nearly seventy years. Today it is a National Register-listed museum operated by Orange County Parks, with restored courtrooms, county history exhibits, and a stunning two-story atrium.

Old Towne Orange
Old Towne Orange is a near-perfectly preserved 19th- and early-20th-century town, organized around the Plaza Park traffic circle. More than 1,300 historic buildings remain — Victorian and Craftsman homes, the original 1880s commercial blocks, antique stores, and the Watson Drug Store, the oldest continuously operating drugstore in Orange County (founded 1899).

Disneyland Park
Built on former orange and walnut groves and opened on July 17, 1955, Disneyland reshaped Anaheim and Orange County into a world-class tourism destination. The original Sleeping Beauty Castle, Main Street U.S.A., and Walt's apartment above the firehouse are still in place — a working civic and cultural landmark of postwar California.

Crystal Cove Historic District
Tucked into a cove between Newport Beach and Laguna Beach, the Crystal Cove Historic District preserves 46 wood-and-stucco beach cottages built between 1920 and 1940. Once a rental colony for Hollywood writers and Newport families, it is now part of Crystal Cove State Park, with restored cottages available for overnight stays and a beachfront café in the original 1940s structure.

Richard Nixon Presidential Library
The library and museum sit on the original Yorba Linda lemon farm where Richard Nixon was born in 1913. The fully restored 1912 farmhouse — built by his father from a Sears mail-order kit — still stands on the grounds, alongside Nixon's presidential Marine One helicopter, a full-scale replica of the East Room, and rotating exhibits on Cold War-era U.S. history.

Bowers Museum
Founded in 1936 in a Spanish Revival building in downtown Santa Ana, the Bowers Museum has hosted blockbuster exhibitions on Tutankhamun, the Terra-Cotta Warriors, and California's Native peoples. Its permanent collections of Pre-Columbian, California, Pacific Rim, and African art make it one of the most internationally engaged museums between LA and San Diego.

Modjeska House (Arden)
Tucked into the oak woodlands of Modjeska Canyon, 'Arden' is the country estate of legendary Polish-American Shakespearean actress Helena Modjeska, designed in 1888 by Stanford White (architect of New York's original Madison Square Garden). Now a National Historic Landmark operated by OC Parks, with original interiors and gardens preserved.

Anaheim Packing District
Built in 1919 by the Sunkist cooperative as a Valencia orange packing facility, the Packing House sat empty for decades before being restored in 2014 into one of California's most successful adaptive-reuse food halls. More than two dozen independent food concepts operate in the original wooden trusses and concrete loading bays — a direct, walkable connection to OC's citrus past.

A Culture Built in Layers
Orange County's identity isn't a single story — it's six overlapping ones. Each is alive in the region today.

Tongva & Acjachemen Living Heritage
The Tongva (Gabrieleño) and Acjachemen (Juaneño) peoples have lived across what is now Orange County for thousands of years. Their place names, ceremonies, and stewardship of the land remain a present, foundational layer of OC's identity.

Mission & Mexican-Californio Roots
From the bell wall at Mission San Juan Capistrano to Los Rios Street to the Yorba and Sepúlveda adobes, OC's Spanish and Mexican rancho era is still visible across cities like San Juan Capistrano, Santa Ana, and Yorba Linda.

Citrus & the Sunkist Era
From the late 1800s through the 1940s, Orange County was one of the great citrus capitals of the world. Sunkist was born here, and the old packing houses and Valencia-orange landscapes still shape neighborhoods like Old Towne Orange and the Anaheim Packing District.

Beach & Surf Culture
42 miles of Pacific coastline have built a culture of surfing, beach volleyball, and outdoor life from Seal Beach to Huntington Beach to Newport, Laguna, Dana Point and San Clemente — a defining lifestyle layer of modern OC.

Disneyland & the Tourism Identity
Since 1955, Disneyland has reshaped Anaheim and given Orange County a global brand identity — anchoring a tourism economy that includes Knott's Berry Farm, the Anaheim Convention Center, the Discovery Cube, and dozens of nearby resorts.

Multicultural Modern OC
Today's Orange County is home to one of the largest Vietnamese-American communities in the world (Little Saigon), one of the largest Korean-American communities in the U.S., and substantial Mexican-American, Persian, Indian, and Filipino communities — a multicultural layer that defines modern OC life.
