On Saturday and Sunday night, hundreds of bonfires were lit to mark Eleventh night – a tradition observed by many unionist communities on the eve of the Twelfth.
The bonfires commemorate the actions of King William III’s supporters in 1690, who lit fires across the countryside to welcome him and guide him to the battle site.
Most Eleventh night bonfires pass without incident, but some are controversial due to their height or location, or because they contain symbols considered offensive.
This year the bonfire in Moygashel in County Tyrone caused controversy again when an effigy of a mosque was burnt on Thursday night.
A man died after falling from an unlit bonfire in east Belfast on Friday night, a death which the bonfire organisers described as a “tragic accident”.
Elsewhere, some bonfires have caused controversy because they include the display of contentious images and the burning of sensitive symbols such as national flags.
On Sunday, effigies of rap trio Kneecap were placed on another bonfire in Donegall Pass, south Belfast, along with a Palestinian flag, Celtic Football Club flag and Irish tri-colour.
More than £1.4m was spent by the Northern Ireland Housing Executive in the past four years to protect and repair homes and property close to bonfires.
