“The Los Angeles County Museum of Natural History quietly has begun a $115-million fundraising campaign and five-year renovation project to update the oldest segment in its string of connected structures in Exposition Park. The renovations, already underway, include restoring the museum’s original 1913 rotunda, letting in a lot more light and girding it with modern earthquake protection. Existing exhibition spaces in the rotunda building and adjoining 1920s-vintage areas will be reconfigured to create six new galleries.”
