What happened November 1605 AD

The medieval House of Lords chamber, which had been the target of the failed Gunpowder Plot of 1605, was demolished as part of this work in order to create a new Royal Gallery and ceremonial entrance at the southern end of the palace.

The rising popularity of Guy Fawkes Night (5 November) from 1605 onward, saw many Halloween traditions appropriated by that holiday instead, and Halloween's popularity waned in Britain, with the noteworthy exception of Scotland.
