January 17, 2026 -Lecture: Where it All Began, El Presidio of San Diego
Lecture: Where it All Began, El Presidio of San Diego
Speaker: Author and Historian Richard Carrico
Join Richard Carrico as he explores Alta California’s first Spanish settlement at Presidio Hill in San Diego. Founded in 1769, the ruins of the mission and fort are now beneath the landscaped hills in Presidio Park. Carrico’s newly released book tells the stories of those who lived at the presidio, including the Kumeyaay people. One highlighted story is of Sinusin, a Kumeyaay woman who married a Spanish soldier and raised her family at the presidio. Carrico's extensive research draws from Spanish archives, Kumeyaay oral traditions, and nearly a decade of archaeological work at the site. In the ABDNHA Library. General Public: $12, Members: $10, Volunteers: $8. Register online or at the Nature Center, 760-767-3098.
