 When any new Knights of the Garter are due for installation, an investiture ceremony is held in the Throne Room of Windsor Castle on the morning of Garter Day.This ceremony is attended by all Knights Companions of the order, wearing the ceremonial habits and garter insignia, and also by their spouses.The wording of the oath sworn by the new knights at this ceremony and of the Admonitions addressed to them in turn by the prelate and chancellor of the order when the several items of insignia are placed upon them are extremely similar to the traditions of the past.
