TOWER OF LONDON (cont.)
The terrified Royal Family fortified themselves in the "impregnable" Tower
of London. Heroically, the king at the time, young Richard II, a boy of 14,
rode out to parlay with them. But, a miscreant called Wat Tyler with a
band of friends managed to persuade the gatekeepers to let them into the
Tower. They ransacked the royal kitchens, found the Queen Mum’s apartments
– forcing her to give them all a kiss – then went looking for "the king’s evil
advisers". One of whom – Simon Sudbury, the Archbishop of Canterbury – they
found praying frantically for his soul in St John’s Chapel in the White Tower. They
grabbed him and dragged him out through the gate, up to Tower Hill and there
decapitated him using blunt agricultural implements

Thus starting the tradition of beheading nobility in public on Tower Hill.
(Royal beheadings were at
least afforded some privacy –
these took place in front
of witnesses behind
the Tower’s walls – on
picturesque Tower Green)
