Looking at the numerous photos taken by photographers on that momentous day, many drew attention to the note that lay in the wreath on the coffin lid of Queen Elizabeth II.

It was a note from the Queen's son, King Charles III.

It read: "In loving and devoted memory, Charles R."

You may have noticed that Queen Elizabeth II and King Charles III put the letter R in their signature (so does Queen Consort Camilla).

The king's new signature is linked to his new status as a sovereign.

The "R" after his name stands for Rex, which means "king" in Latin, a traditional signature of a monarch dating back to the 12th century.

When using Queens, the letter "R" stands for "Regina" or "Queen" in Latin.

During her historic reign, Queen Elizabeth signed official communications as "Elizabeth R.".

The Prince and Princess of Wales also left notes for the deceased monarch.

She wrote notes by hand.

Two cards with William and Kate's monograms were hidden among the family wreaths along the chapel aisle.

However, their content is not disclosed.

No less interesting was the wreath that you could see on the coffin of the monarch.

The flowers were handpicked by Elizabeth and included flowers and foliage cut from the gardens of Buckingham Palace, Clarence House and Charles' country house, Highgrove House.

The wreath used English oak, dahlias, garden roses, autumn hydrangeas, rosemary, geraniums and sprigs of myrtle, cut from the same myrtle bush that was used in Princess Elizabeth's 1947 wedding bouquet.

Well, very symbolic.
