The Dominion War Memorial was a monument to the dead of the Dominion War that was built on the Klingon world Narendra III.
Chancellor Martok intended the memorial to honor all these killed in the war and J'lang, the sculptor, included figures from the Klingon military, the Romulan military and Starfleet. (TNG - The Brave and the Bold, Book Two novella: The Final Artifact)
