Participants and spectators enjoyed one of the hottest Twelfths in recent years
Crowds have lined the streets of cities, towns and villages all over Northern Ireland on Saturday to attend Twelfth of July parades.
Thousands of Orange Order members take part in the annual marches to commemorate the anniversary of the Battle of the Boyne in 1690.
The event is also a celebration of Protestant traditions and Ulster-Scots heritage, and comes after bonfires were lit across Northern Ireland on the Eleventh night.
Here's a look at some of the best pictures from the celebrations.
