Each year, London marks the historic moment when Guy Fawkes and his motley crew attempted to blow up the Houses of Parliament and King James I in the Gunpowder Plot of 5 November 1605 – the day became known as Guy Fawkes Day, or more commonly Bonfire Night.
Every November, bonfires are lit on which effigies known as “guys” are burned; while the skies are filled with colourful fireworks. It’s also a time to enjoy traditional Bonfire Night food and drink, alongside music, funfairs and family activities.
