A large federal building and courthouse complex was constructed in 1993 as part of an Oakland revitalization project. In 1999, President Bill Clinton signed a bill authorizing that the building be renamed to the Ronald Vernie Dellums Federal Building complex. Ronald Vernie Dellums was a prominent civil rights activist, a congressman, and the 48th mayor of Oakland.
The building has a sculpture garden that pays tribute to civil rights activist Judge Donald Pitts McCullum, whom was born in Little Rock, Arkansas. Judge McCullum was a member of the NAACP and took legal actions to end the segregation of high schools in Oakland.
Inside of the federal complex is a wealth of photos of the Bay Area including some of the production of Chevrolet vehicles in the early 1900s and Lawerence at the site of the construction of an extension of the National Livermore Laboratory within the University of California Berkeley campus.
Other photos showed the early history of the east bay.
Other photos revealed life for the Japanese Americans who were interned during World War II, Unser Franklin Dwight Roosevelt’s executive order.
There were photos that showed the construction of the Oakland Coliseum, the first BART station, as well as a car factory that was eventually bought out by Tesla in 2010. 
Another photo showed President George H.W. Bush visiting the Cypress Street viaduct that had collapsed after the 1989 earthquake.
