Diego Sepulveda Adobe in Costa Mesa, CA: What to Expect

Tucked away in Costa Mesa’s Estancia Park lies a hidden gem of Orange County’s history: The Diego Sepulveda Adobe. This historic adobe, dating back to the early 1800s, offers visitors a rare opportunity to step back in time. Once serving as a waystation for travelers and later a ranch house, the adobe has been carefully preserved, most recently by the Costa Mesa Historical Society, to showcase its fascinating past.

The adobe’s rustic charm is complemented by its simple yet significant design—a one-story structure with thick adobe walls, small windows, and a traditional tile roof. Inside, visitors can explore displays featuring historical artifacts, photographs, and informational panels that paint a vivid picture of life in early California.

The park surrounding the adobe features green lawns, mature trees, and views of Costa Mesa’s skyline. It’s an ideal place for a picnic or a leisurely stroll, offering a quiet retreat in the middle of the city.
