The Proclamation Gallery is a part of St James's Palace in London, England. It is used after the death of a reigning monarch. The Accession Council meets to declare the new monarch from the deceased monarch's line. Once the monarch makes a sacred oath to the council, the Garter King of Arms steps onto the Proclamation Gallery, which overlooks Friary Court to announce the new monarch.
