On Thursday 8 September, news arrives that would change the nation’s history. The death of Her Majesty Queen Elizabeth II is announced after 70 years on the throne. It’s a time of deep sadness for the Tower staff and for the yeoman warders, some of whom have met the Queen in their role as royal bodyguards. As a royal palace, with special links to the Royal Household, the Tower enters a two-week official period of mourning.
