In 1949, the Port of Long Beach gave this old oil derrick to Captain Jacob Jacobsen to use as a radar tower. This was the first private, shore-side radar in the United States! At the time, radar was new technology. The oil derrick is estimated to be built before 1910! Because the tower doesn't meet earthquake engineering standards, in 2022 JPS decided to replace the tower.
