On entering Glastonbury Abbey, one of the first buildings you come to is the charming little St. Patrick’s Chapel. Here is a mural which recalls the last days of the Abbey in 1539.

At the time of the Dissolution programme which began in 1534, Richard Whiting was the gentle and respected bishop of Glastonbury Abbey, the second richest religious institution in England, with around 100 monks. The story is well told by Wikipedia here.
In essence, Whiting was conned in the early years that the programme would only affect smaller institutions. By 1539 Glastonbury was the only remaining abbey in Somerset. On being told to surrender the Abbey, Whiting refused, acting legally correctly. Naturally, the Glastonbury leaders took steps to keep the abbey’s treasures safe. This was then turned round by the church commissioners, and ultimately Thomas Cromwell acting on behalf of King Henry VIII, as evidence of treason. His defiance was simply not acceptable to the all-powerful king. There was no due process. Whiting was convicted in secret, and executed on Glastonbury Tor with two of his team.
The mural shows three gibbets on Glastonbury Tor, where the 3 men were hanged, drawn and quartered. These were savage times, and of course Whiting was not the first religious leader to be so treated.
Whiting is considered a martyr by the Catholic Church which beatified him over 300 years later.
