Britain’s Royals Remember Queen Elizabeth II on What Would Have Been Her 100th Birthday

Britain’s royal family will mark what would have been the late Queen Elizabeth II’s 100th birthday by unveiling comprehensive plans for a new charity and memorial in central London.

Several events are planned for Tuesday to honour Britain’s longest-serving monarch, who died nearly four years ago at the age of 96.

Her son King Charles III and his wife Queen Camilla will visit the British Museum in London to view designs of the planned memorial, while her daughter Princess Anne will officially open the Queen Elizabeth II Garden in Regent’s Park, London. In a video posted on the Royal Family’s YouTube channel, Charles also reflected on his mother’s legacy.

“Her near century was one of remarkable change, and yet, through each passing decade, through every transformation, she remained constant, steadfast and wholly devoted to the people she served,” the king said in his personal message.
