Twelfth: parades taking place across Northern Ireland
The biggest demonstration is in Keady where the Co Armagh lodges are gathering
Traditional Twelfth parades are well under way across Northern Ireland.
Thousands of Orange Order members accompanied by bands are heading to various venues.
The festivities will be spread across 19 main locations to mark the 334th anniversary of the Battle of the Boyne.
These are at Augher, Ballymena, Belfast, Carnlough, Coagh, Coleraine, Cullybackey, Dromara, Dundonald, Dundrum, Glengormley, Lisburn, Keady, Kesh, Kilkeel, Maghera, Rasharkin and Sixmilecross.
The biggest of the gatherings is at Keady where the Co Armagh demonstration takes place.
Indeed, the Orange Order this is firmly established as the largest Orange gathering in the world.
Earlier, an Orange Order feeder parade passed the Ardoyne shops in north Belfast without incident on Saturday.
DUP leader Gavin Robinson will address the parade in Belfast while Northern Ireland's deputy First Minister Emma Little-Pengelly will deliver a speech at the Lisburn parade.
Downtown Radio & Cool FM spoke to County Grand Master Spender Beattie (see below).
Of all the loyal order parades to take place on Saturday, about 30 have been officially categorised as sensitive by the Parades Commission.
Locations of sensitive parades this year include Belfast, Coleraine, Keady, Dunloy, Rasharkin, Strabane, Newtownabbey, Maghera, Newtownbutler, Portadown, Glengormley and Bellaghy.
More than 4,000 police officers and police staff will be working on July 12.
On the 11th night, about 1,200 officers were deployed to monitor public safety at bonfires.
Chief Constable Jon Boutcher has urged mutual respect in the marking of events.
He said: "Our officers will be on the ground throughout the weekend, working in partnership with community leaders, event organisers, and local representatives to support lawful, peaceful and family-friendly events. However where necessary, we will take firm and proportionate action to keep people safe.
"Our priority remains the safety and wellbeing of everyone."
On Sunday an Orange Order parade will return past the Ardoyne shops but will be restricted to one band and 50 members of the order.
It is a return parade at the former flashpoint which traditionally took place on the evening of July 12, often resulting in violent scenes.
Meanwhile, the traditional July 13 events organised by the Royal Black Preceptory in the village of Scarva, Co Armagh will take place on Monday.
The event includes a parade as well as a sham fight between actors playing rival monarchs William and James.
