Sonoma Plaza is at the heart of the town and is one of its most iconic landmarks. This historic plaza, initially established in the 19th century, is surrounded by charming buildings showcasing Spanish Colonial architecture.

Mission San Francisco Solano is an essential part of Sonoma’s historical and architectural identity. This mission, founded in 1823, was the last and northernmost mission built in the California mission chain. Its adobe structure, complete with simple yet striking design elements, reflects the Spanish and Mexican influences prevalent during its time. Inside, the mission features original artifacts, a small museum, and exhibits detailing the area’s early history. The combination of its architecture and cultural significance offers visitors a glimpse into Sonoma’s roots.

Located near Mission San Francisco Solano, the Sonoma Barracks is another historical gem. Constructed in the 1830s, this two-story adobe building originally housed Mexican soldiers. Its thick adobe walls, wooden beams, and modest design characterize early Californian architecture. The building’s purpose evolved as a political and military hub during the Bear Flag Revolt. Today, the Sonoma Barracks is a museum that preserves the structure's architectural and historical significance.

The home of General Mariano Guadalupe Vallejo, a significant figure in California’s history, is a prime example of Sonoma’s architectural heritage. Known as Lachryma Montis, Vallejo’s home was built in the mid-1800s and reflects a blend of Victorian and Greek Revival styles. The two-story house features elegant columns, wide verandas, and decorative details that set it apart. The surrounding grounds include a small vineyard, gardens, and additional outbuildings that give visitors a sense of life in Sonoma during Vallejo’s time.

The Sebastiani Theatre, located just off Sonoma Plaza, is a beloved cultural and architectural landmark. Built in 1933, the theater showcases classic Art Deco design, with intricate moldings, bold colors, and a marquee that lights up the town center. Its interior is just as striking, with vintage charm and modern functionality. This landmark perfectly embodies the blending of old-world elegance and contemporary utility that defines much of Sonoma, CA architecture.

As the oldest family-owned winery in California, Gundlach Bundschu is an architectural treasure. The property’s main building is a beautiful example of rustic winemaking architecture, complete with stone walls and wooden accents that complement the surrounding landscape. The winery blends functionality with style, allowing visitors to explore the art of winemaking in a setting that respects history and nature.

Buena Vista Winery is another iconic destination in Sonoma. Founded in 1857, it is California’s first premium winery. The stone winery buildings, surrounded by picturesque vineyards, feature a European-inspired design that reflects the vision of its founder, Agoston Haraszthy. The interiors have been modernized, but the exteriors retain their historical charm. Visitors often appreciate the winery's attention to preserving its history while catering to modern tastes.
