On Saturday a royal official has publicly proclaimed King Charles III as Britain’s new monarch during a ceremony at St. James’s Palace.

David White, the Garter King of Arms, read the proclamation from a balcony at the London royal residence flanked by trumpeters in gold-trimmed robes.

Gun salutes rang out in Hyde Park, at the Tower of London and at military sites around the U.K. as the proclamation was made.

Scarlet-robed soldiers in the palace courtyard presented arms and doffed their bearskin hats in a royal salute.
