Set in the foothills of the Santa Ana Mountains, Rancho Santa Margarita is a vibrant city with the unique quality of an urban village. Although incorporated on January 1, 2000, making it one of California's youngest cities, it has a rich and intriguing history that dates back to the origins of the Golden State. During the late 1800s, the original ranch covered 230,000 acres, making it one of the largest in the Southwest. With many never-before-seen images, this book captures the essence of this fascinating story of the city, including the Spanish expedition in the 1700s, the Mexican governance of the land, the ownership of the area by the O'Neill family, the ranch activities of the 1960s, and the building of city landmarks in the 1980s, including the development of the most scenic lake in Orange County.
