Today, you can still see the place where Guy Fawkes was executed by hanging, in the Old Palace yard adjoining the Palace of Westminster – ironically just a few yards from where he intended to detonate tons of explosive. There is also a small exhibition about the plot on display in the medieval Westminster Hall, one of the few parts of the Palace of Westminster that remains unchanged since that day. One of the rather gruesome displays depicts Fawkes’ severed head, along with the heads of the other plotters that were displayed upon spikes throughout London.
And today – 400 years later - the Palace guards still search the cellars of the Houses of Parliament before every state opening of Parliament to make sure there are no explosives hidden there – although one hopes this is carried out as a quaint custom rather than an actual deterrent.
