As Britain prepares for a second COVID-19 lockdown, her Majesty Queen Elizabeth II traveled from Windsor Castle to London to mark the centenary of the burial of the Unknown Soldier.

Queen Elizabeth II (94) traveled from Windsor Castle to Westminister Abbey on Wednesday to mark the centenary of the burial of the Unknown Soldier. Wearing black the Queen was greeted by the Dean of Westminster Abbey, The Very Reverend David Hoyle during this unannounced trip ahead of the UK's COVID-19 lockdown. 

The anniversary of the Unknown Soldier's burial is Nov 11, however, due to COVID commemorations had to take place in advance. 

The Court Circular, on Nov 4, reads:

"The Queen this morning commemorated the Centenary of the burial of the Unknown Warrior at Westminster Abbey, London SW1, and was received at the Great West Door by the Dean of Westminster (the Very Reverend Dr. David Hoyle).

"The Rt Hon Boris Johnson MP (Prime Minister and First Lord of the Treasury) had an audience of Her Majesty via telephone this evening."

Queen Elizabeth was photographed leaving Windsor Castle on Wednesday and returned two hours later. The Queen was wearing all black, which is usually only wears during periods of mourning. 

The tomb of the Unknown Soldier, officially called the "The Tomb of The Unknown Warrior", is the burial site of an unidentified British soldier killed on a European battlefield during the First World War.

He was buried in Westminster Abbey, London on Nov 11, 1920, simultaneously with a similar interment of a French unknown soldier at the Arc de Triomphe in France, making both graves the first to honour the unknown dead of the First World War.
