ROOTED HERE
Before the harbor day.
A whole city’s story.
Chumash homelands, agricultural roots, a changing downtown and a working coast. Follow a few of the threads that shaped Oxnard.
People made the city.
The sugar beet industry drew Chinese, Japanese and Mexican workers to Oxnard. Farms, shops, restaurants and other businesses grew alongside the factory. That history belongs to the people who worked and built communities here, as well as to the families whose names appear on buildings. Read Visit Oxnard’s account.
