St Patrick's Day: Festivities to climax on Monday
Saint Patrick's Day festivities are due to culminate in Northern Ireland on Monday.
In Omagh, the festival reaches its climax with an open air concert and parade from 13:00 GMT.
Last year, the event attracted about 15,000 people.
It comes at the end of three days of celebrations across Northern Ireland, with many parades taking place on Sunday in Belfast, Armagh, Downpatrick, Enniskillen and Londonderry.
One of the biggest parades took place in Belfast, where thousands lined the streets.
It was followed by an open air concert, headlined by the X-Factor's Amelia Lily, at Custom House Square.
Meanwhile, almost 500,000 people lined the streets of Dublin to watch the biggest parade on the island of Ireland.
