Natural History Museum of Los Angeles County
The museum joins deep time to an urban nature lab, California history, mineral science, and a research collection far larger than what is displayed.

The museum joins deep time to an urban nature lab, California history, mineral science, and a research collection far larger than what is displayed. Its older dioramas and newer community interpretation reveal changing museum practice. Useful scale comes from three specifics: opened, 1913; campus, Exposition Park; and collections, 35 million objects.
Begin with the Dinosaur Hall’s evidence, then move to Becoming Los Angeles to connect natural systems with human land use. The museum and nearby California Science Center use separate admission systems; seasonal butterfly and spider pavilions require timed add-ons. Close attention to Dinosaur Hall, Gem and Mineral Hall, and Becoming Los Angeles turns the visit from a collection of sights into a connected argument about this place.
