There are currently 16 official missions in California. These missions were established by Spanish colonizers during the late 18th and early 19th centuries as a way to spread Christianity and introduce European agricultural techniques to the region. The most famous of these missions is the Mission San Juan Capistrano, known for the annual return of the swallows.
The missions were also established as a way to expand Spanish influence and control in the region. Each mission was typically built a day's journey apart, allowing for easier travel and communication between them. The mission system played a significant role in the history and development of California, and many of the missions still stand today as historic landmarks and popular tourist attractions.
Visiting these missions can provide a fascinating glimpse into California's past and the influence of Spanish colonization on the region. Many of the missions offer guided tours and educational programs, making them an excellent destination for both tourists and locals alike.
