On April 22, 1913, a "Century Chest" was buried in the basement of the First English Lutheran Church (now the First Lutheran Church of Oklahoma City) at 1300 North Robinson. The ceremony was witnessed by a capacity crowd including Governor Lee Cruce and other notable Oklahoma residents.
Through a century of dutiful vigilance the congregation of the First Lutheran Church has guarded the Century Chest in order that on April 22, 2013, the chest would be unearthed and the past would come alive. The church has partnered with the Oklahoma Historical Society to ensure the treasures of 1913 are preserved and exhibited at the Oklahoma History Center.
This footage from OETA captures the entire Century Chest ceremony, April 22, 2013. The opening of the chest starts around 1 hour 10 minutes in.
