The Washington National Cathedral is replacing stained glass windows featuring Confederate symbols with racial-justice themed pieces in a display created by two Black American artists, the site said on Thursday.

New windows created by artist Kerry James Marshall, a Black American man, will aim “to share a new and more complete story, to tell the truth about our past and to lift up who we aspire to be as a nation,” said the Rev. Randolph Marshall Hollerith, dean of the cathedral.

The “racial-justice themed” windows were expected to be completed in 2023 and permanently installed, said a cathedral spokesman.

The cathedral also announced that Elizabeth Alexander, a Black poet who spoke at then President Barack Obama’s inauguration, will write a new piece “that will be inscribed in stone tablets alongside Marshall’s window installation, overlaying the previous stone tablets which venerated the lives of Confederate soldiers.”
