Tens of thousands of loyal order members and 600 marching bands are taking part in the annual Twelfth of July festivities in Northern Ireland.
The largest Orange Order parades are under way in Belfast, as well as the Co Antrim coastal town of Carrickfergus, which boasts historic links to King William of Orange, who triumphed over King James II at the Boyne in 1690.
Ballymena, Newtownstewart, Londonderry and Killylea are also among the 18 locations hosting processions to mark the 334th anniversary of the Battle of the Boyne.
Politicians’ election posters were placed on some of the bonfires.
The Northern Ireland Fire and Rescue Service said it dealt with more than 100 emergency 999 calls since 6pm on Thursday evening.
Brian Stanfield, Assistant Chief Fire and Rescue Officer said: “It has been a relatively quiet 11th night.
“This resulted in our firefighters attending 78 operational incidents, 37 of which were bonfire related.
“During this period, the number of emergency calls received was down 25% when compared to 2023.
“Peak activity was between 10pm and 1am and normal emergency response across Northern Ireland was maintained.”
“Across the 18 venues, we will have tens of thousands of men, women and young people taking part in an event which has been faithfully maintained for well over 200 years,” he said.
“Many thousands more will line the streets of host cities, towns and villages.
“There is simply no other event on these islands that can bring such vast numbers of people on to the streets as our processions, either by taking part or simply to watch them go by.”
“It is about publicly expressing our faith, our culture, our heritage. It is about celebrating, respectfully, our identity,” he said.
“In an increasingly diverse Northern Ireland, it is important that the Orange culture is celebrated positively, and afforded respect by all as we build a truly shared, tolerant society.
“As the leader of unionism, I will work across government in London and Stormont, as well as local council, to ensure this cultural celebration is supported and its potential harnessed for Northern Ireland.
“I wish all those taking part in or attending parades across Northern Ireland today, and indeed tomorrow at Scarva, a very enjoyable day.”
The routes of certain Orange parades became intense friction points during the Troubles, often leading to widespread rioting and violence.
The number of flashpoints has reduced significantly in the peace process years.
July 11 and 12 remain the busiest days of the year for the Police Service of Northern Ireland, which is expecting to deploy 4,000 officers and staff, about two-thirds of the force, in a public safety operation.
The cost of the policing operation is expected to be about £4.5 million.
