Palace officials say the state funeral for Queen Elizabeth II will take place on Sept. 19 at Westminster Abbey in London after the public gets an opportunity to pay their last respects.

Elizabeth, the nation’s longest-reigning sovereign, died Thursday.

Details on the 96-year-old queen’s funeral will be released later, but organizers on Saturday described the ceremony as a “a fitting farewell to one of the defining figures of our times.’’

Palace officials said there would be opportunities to see the late sovereign’s oak coffin as it journeys from Balmoral Castle in Scotland to Edinburgh and again in London, where her body will lie in state for four days starting Wednesday.

Earlier, King Charles III was officially announced as Britain’s monarch.
