An Investiture is a very special day when an individual who has been awarded an honour receives their award in person, usually at a ceremony at one of the Royal residences.
Investitures are normally carried out by The Queen, but The Prince of Wales also carries out investitures on behalf of Her Majesty.
As well as receiving awards within one of the Orders of Chivalry, recipients may also attend to receive a decoration for gallantry such as the George Cross or The Queen's Gallantry Medal.
Occasionally, an award for gallantry may be made posthumously.
