BuyThe story of Sonoma
Sonoma, California, is a place where history, viticulture, and a relaxed pace converge. Approximately 45 miles north of San Francisco, the city is set within the 17-mile-long Sonoma Valley, itself part of the larger Sonoma County. The region is globally celebrated for its wines, a legacy that traces back to the early 19th century. Yet, Sonoma offers more than just a taste of its celebrated vintages; it's a destination that invites exploration of its historic town square, diverse culinary scene, and scenic natural landscapes.
The city of Sonoma grew around Mission San Francisco Solano, established in 1823, and was further shaped by General Mariano Guadalupe Vallejo, who developed the surrounding pueblo. Today, the central Sonoma Plaza, the largest in California, remains a focal point, hosting events and offering a shaded expanse for visitors. Beyond the plaza, the wider Sonoma Valley and County present opportunities for outdoor activities, from hiking among redwoods to exploring the coastline.
From Indigenous Lands to Mexican Frontier
For at least 12,000 years before European arrival, the Sonoma Valley was home to Indigenous peoples, including the Pomo-Kashaya, Wapo, and Patwin. European influence began to shape the area in the early 19th century. In 1823, Padre José Altimira founded Mission San Francisco Solano, the 21st and final California mission, and the only one established under independent Mexico. The mission's establishment was partly intended to deter Russian expansion from their outpost at Fort Ross.
Following the secularization of the missions in 1834, Californio statesman General Mariano Guadalupe Vallejo founded the Pueblo of Sonoma on the former mission lands in 1835. Vallejo, who had been the commandant of the Presidio in San Francisco, moved his garrison to Sonoma, making it the headquarters of the Mexican provincial frontier of the north. He oversaw the development of the town around the plaza, laying the groundwork for its agricultural economy, particularly grape growing and winemaking.
The Bear Flag Revolt and American Annexation
Sonoma's role in California's transition to statehood is significant. In June 1846, a group of American immigrants, seeking to establish their own California Republic, seized the Pueblo of Sonoma in what became known as the Bear Flag Revolt. They raised a flag depicting a bear and a star in Sonoma Plaza, and the Sonoma Barracks, built by Vallejo to house Mexican soldiers, became the headquarters for this short-lived insurrection. Just 23 days later, in July 1846, the U.S. flag was raised at the barracks, signaling the end of the California Republic and the beginning of California's American territorial period.
Post-Statehood Development
After California became a state in 1850, Sonoma was initially incorporated as a city. However, General Vallejo later had it unincorporated in 1862, a move that benefited landowners like himself. Sonoma was re-incorporated as a city in 1883. The Sonoma Barracks continued to serve various purposes, housing U.S. forces until 1852, and later being used by Vallejo as a winery. Today, the Sonoma Barracks and Mission San Francisco Solano are part of the Sonoma State Historic Park, preserving these pivotal sites for visitors.
Begin your exploration at the Sonoma Plaza, the largest town square of its kind in California. This expansive, tree-shaded park is surrounded by historic adobe buildings that tell the story of early California. On the plaza's northeast corner, you'll find Mission San Francisco Solano, the last of the California missions, offering a glimpse into the region's Spanish and Mexican heritage. Adjacent to the Mission are the Sonoma Barracks, a two-story adobe structure that served as military quarters and the headquarters for the Bear Flag Revolt. The barracks now houses exhibits and a documentary on Sonoma's history.
For art enthusiasts, Sonoma offers several galleries, including Lori Austin Gallery Sonoma and FLOWER + HEWES Art Gallery, showcasing contemporary American and international art, as well as works from California-sourced artists. The Arts Guild of Sonoma also features local artists. Beyond the town center, consider a visit to Jack London State Historic Park for hiking and history, or explore the coastal redwoods at Armstrong Redwoods State Natural Reserve. For family-friendly activities, TrainTown Amusement Park offers miniature train rides, and Safari West provides an African safari experience in Santa Rosa.
Sonoma offers a pleasant experience year-round, thanks to its warm-summer Mediterranean climate. The warm season, from early June to mid-October, brings average daily high temperatures above 78°F, with July being the hottest month. This period, especially September and October, is peak tourism season, coinciding with the grape harvest and lively fall foliage. Spring (April to May) is also highly recommended, with comfortable temperatures in the 60s-70s, green landscapes, and fewer crowds. Winter (December to February) is the quietest and wettest period, with mild temperatures in the 50s and 60s, offering a chance for more intimate winery experiences.
Sonoma is easily accessible by car, a short drive north of San Francisco. While there's a regional airport (Charles M. Schulz Sonoma County Airport, STS), flying into Sacramento can sometimes be a more economical option. A car is generally recommended for exploring the wider Sonoma Valley and County. Accommodation options range from luxury hotels and resorts to charming bed and breakfasts and inns. Popular choices include the El Dorado Hotel, MacArthur Place Hotel & Spa, and The Lodge at Sonoma. For those looking to explore beyond wine tasting, consider hiking at Sonoma Valley Regional Park or Jack London State Park, or visiting the coast. Many wineries are also family-friendly, offering activities like bocce ball and picnic areas.
