10 Must-Visit Historic Sites in San Diego

California’s history began long before it became a state, with the establishment of Spanish missions in the late 1700s and key settlements in cities like Monterey and Santa Barbara. These missions formed the backbone of Spanish colonization. They fostered cultural exchanges and conflicts with Native American communities. Meanwhile, coastal cities like San Francisco flourished during the Gold Rush, and became economic and cultural powerhouses. Among California’s historic cities, San Diego stands out as the location of the first Spanish mission, Mission San Diego de Alcalá, in 1769. Its strategic position shaped its role as a military and trade hub, laying the foundation for its unique blend of Native, Mexican, and American influences. Today, San Diego boasts a rich array of historic sites, from missions and military landmarks to architectural gems. Here are ten historic sites that are a must-visit in San Diego.

Old Town San Diego State Historic Park, established in 1968, preserves the heritage of San Diego from 1821 to 1872, showcasing its evolution from a Mexican pueblo to an American settlement.

You’ll have the chance to explore original adobe structures, such as the Casa de Estudillo, a restored 1827 adobe house that offers insight into early Californian life.

The park also features museums, including the San Diego Union Museum, which houses a mid-19th-century period newspaper office and print shop, and the Seeley Stable Museum, displaying horse-drawn buggies and western memorabilia.

Often referred to as the “Mother of the Missions,” it served as the foundation for the state’s network of 21 Spanish missions. Located in San Diego, it marks the birthplace of Christianity on the West Coast.

What sets this mission apart is its rich and complex history. It was not only a religious site but also a hub of cultural exchange, and at times, conflict, between Spanish settlers and the indigenous Kumeyaay people. The original adobe structure faced attacks and abandonment before being rebuilt in 1813. Today, its bell tower still chimes, echoing centuries of resilience and faith.
