Catafalque of Krzysztof OpaliÅski, 17th century. A catafalque is a raised bier, box, or similar platform, often movable, that is used to support the casket, coffin, or body of the deceased during a funeral or memorial service.
Following the precedent set by Lincoln's lying in state, the catafalque has been preserved and honored, used only to hold the coffins of presidents and others deemed by the Congress to be worthy of laying in state in the Rotunda, or used in the Supreme Court for Justices.
