Thousands of Orangemen and woman have been marching across Northern Ireland to mark King William III's 1690 victory at the Battle of the Boyne.
Members, bands and supporters have participated in 18 demonstrations as the Orange Order marked the Battle of the Boyne in 1690.
The Orange Order's three 'flagship' parades this year were in Banbridge, Bangor and Larne.
For the first time, most of the shops in Belfast city centre were open.
Belfast city centre manager Andrew Irvine said a programme of on-street entertainment with street performers "from as far away as Australia and America" would entertain shoppers from 1230 BST.
Stores closed again at about 1630 BST when Orangemen and women were making their return journey.
Speaking at the Twelfth demonstration in Bangor, County Down, the Grand Secretary of the Orange Order, Drew Nelson, said nationalists and republicans needed to reach out to Orangemen and women.

He claimed the Order had shown "goodwill and respect to the nationalist and republican community" but that goodwill had not been returned.
Mr Nelson said his organisation had been the target of unprovoked attacks and had been compared to the Ku Klux Klan, a reference which he found offensive.
He said he was laying down a challenge to the political leadership of nationalism and republicanism to show "a greater understanding and tolerance of the Orange institution".
Meanwhile, the grandmaster of the Grand Orange Lodge of Ireland, Robert Saulters, has said Protestants in Northern Ireland are "into a situation of ethnic cleansing".
His comments follow a number of attacks on Orange halls recently.
"The thing is we are in a peace process, I would say we are more into a situation of ethnic cleansing, we had seen that in operation on the Ormeau Road in Belfast in the 1970's and it did work for Sinn Fein /IRA, but don't tell the government that, they may not be able to sleep in their beds at night," he said.
