Each year in Llandudno the council launch fireworks from the Pier on Guy Fawkes night (NOT bonfire night), and they are really rather good. This year I watched from the Camera Obscura by the Orme.
For any non-British people, it's the anniversary of when Guy Fawkes tried to blow up the House of Lords (thus killing the King) by stuffing the basements with gunpowder in 1605. For the last 400 years Britons have marked his being caught, his confession after torture, and then his execution (hung, drawn, and quartered - though he jumped and broke his neck while hanging to avoid the worst bits). Of course that's not very seemly in modern times so it's getting re-branded as Bonfire Night and the burning of the Guy on the Bonfire seems to have disappeared in recent years too. Much like Christmas few people care why any more, they just like the excuse for some sparklies. :) And fair play to that.
