On July 17, 1944, two ammunition ships exploded at Port Chicago, killing 320 sailors and civilians and injuring 390 others in the largest homefront military disaster of World War II. Most of the dead and injured were enlisted African-American sailors.

The National Park Service is establishing a Port Chicago Naval Magazine National Memorial to honor those who lost their lives. The NPS, East Bay Regional Park District and Friends of Port Chicago National Memorial will host a public ceremony at 3:30 p.m. July 17 to commemorate the 72nd anniversary of the Port Chicago explosion and to celebrate the National Park Service centennial.

The ceremony will be at the site of a visitor center planned jointly by the National Park Service and East Bay Regional Park District at the future Concord Hills Regional Park.

It’s an opportunity for friends, family and others interested in the Port Chicago disaster and its aftermath to join in a day of remembrance, celebrate the NPS centennial and visit the site of the planned new regional park. Visitors will be shuttled to the ceremony from the Pittsburg/Bay Point BART parking lot. Those with disabilities or requiring special assistance will be permitted to park on-site.

Tickets to the event are free of charge, but registration is required. To register, visit www.ebparks.org and click on “Port Chicago Commemoration” on the right side of the home page. Or call 925-228-8860, press 2 for the Port Chicago Naval Magazine National Memorial and dial extension 6424.
