Where and when were the missions built?

The missions were primarily built in California by Spanish colonizers between the late 18th century and the early 19th century, specifically from 1769 to 1823. They were established along the California coast, with the first mission, Mission San Diego de Alcalá, founded in 1769. Other notable missions include Mission San Juan Capistrano and Mission San Francisco de Asís, each serving as religious and cultural hubs for Spanish settlers and Indigenous peoples.
