Tens of thousands of people are expected to take part in parades and other festivities across Northern Ireland to celebrate St Patrick's Day.

Among the big events taking place is the parade in Belfast city centre, the centrepiece of a 17-day programme of celebrations running over recent weeks.

In Londonderry, the parade staged by the North West Carnival Initiative, will have 'Forest, Sky and Sea' theme as Derry celebrates the arrival of spring.

Parades are also due to take place in Enniskillen, Downpatrick, Newry and Armagh and, for the first time in seven years, in Ballycastle.

In Downpatrick, early risers made their way to Saul Church – St Patrick's first church in Ireland.

Among them were a group of young people from Missouri who had arrived this morning.

Leading the group was Brittany Shoemake.

"We are a church youth group and we are here for the week and we're here to serve with RIOT (Revival in our Town) in Dundrum," she said.

"We flew in today on St Patrick's Day – so what better day to come and learn about St Patrick and his life and what he means to this country?

"We'll do the communion service here then the walk to Down Cathedral. There'll be a picnic lunch and we'll celebrate the day."

Just a short distance away pilgrims were walking up the steep inclines of Slieve Patrick to the St Patrick monument.

Out for a family walk were three-year-old River and two year olds Freddie and Felix from Killough.

Speaking for the group River said: "I'm going up the big mountain."

The Harte family from Downpatrick were also climbing the hill.

According to mum Maeve: "This is our daughter Grainne and we thought we'd start a family tradition of bringing her up here - getting her used to her culture and to explain heritage."

A large boulder in the grounds of Down Cathedral is covered with floral tributes as the stone marks the reported burial place of St Patrick. It is surrounded by cobbled paving and is marked with a stone plaque.  Other headstones are in the graveyard and the Mourne Mountains can be seen in the distance.

Back in Downpatrick the McGrail family from Lurgan had arrived early and were among the many visitors to the patron saint's grave at Down cathedral.

"We are down from Lurgan, there is nothing on there today," their mother Grace said.

"We're down for the parade and the festival. It's more for the wee man (Rowan) that we are here," their father Darragh added.

"We were at a trad session in Killyleagh the other night and he absolutely loved it."

Thousands of people are expected to pack the town centre for the annual parade on Monday.

Police in Belfast have urged everyone to enjoy the celebrations and "to act responsibly, think of others and have a great St Patrick's Day".

The city's council has been hosting a series of events from the start of March, including the four-day Belfast TradFest celebration of traditional music.

Monday's parade leaves City Hall at 13:30 GMT while the Cathedral Quarter will also be home to a St Patrick's Day Festival Village.

Belfast Lord Mayor Micky Murray said the festivities promise a "multi-cultural celebration of music, culture, the Irish language and community".

Police are encouraging everyone to enjoy the festivities "safely and responsibly".

"If you are socialising, stay with your friends, drink responsibly and make a plan to get home safely," Ch Supt Gerard Pollock said.

He added that people should be especially "mindful of their attitudes and behaviours towards women and girls".

Police are also warning about antisocial behaviour in the university area of the city.

"We have again been working hard to highlight that the residential areas of south Belfast are not a party or nightlife destination," a statement said.

Traffic disruption is expected in Belfast and in Derry throughout Monday's events.

Derry

Derry's parade is due to get under way at 15:00 GMT.

The council's head of culture, Aeidin McCarter, said the local economy would benefit from the influx of visitors to the city.

"We know our hotels are seeing an uplift this weekend with visitors coming to stay, we've lots of people out and about and those people are spending money in our retail and hospitality venues," she told BBC Radio Foyle's North West Today programme.

She said the council had spent up to £30,000 in the parade and other St Patrick's Day events and hoped to increase the investment in carnivals and festivals in the coming years.

Police in the city are also encouraging people to be aware of an initiative launched in 2022 for people feeling unsafe when out socialising to discreetly signal they need help.

It works by encouraging anyone who feels at risk to ask staff in bars, pubs and clubs to Ask for Angela – that notifies bar staff to situations and allows them to step in.

"By asking for Angela, a person who may be feeling uncomfortable or feel unsafe within a licensed venue can quickly alert staff," Supt Pete Brannigan said.

Meanwhile in Ballycastle, momentum is building ahead of the County Antrim town's parade.

Deirdre Goodlad from Glór na Maoile, a local Irish language group, said there had not been a parade there since 2018.

A piper is expected to lead participants through the town to the seafront for live music and a market.

Ms Goodlad said: "Everybody is so excited."

'We decided we needed a parade'

"It happened last year after St Patrick's Day when people said there was nothing on … so we decided we would need a parade," Ms Goodlad said.

"It has been a number of years and we wondered could we do it again."

Volunteers have been organising the event since January.

Ms Goodlad said: "It takes a lot of effort, but it has been worth it so far to have the momentum building in the town."

Organisers expect 1,000 people could turn out to take part in the event and watch it pass through the town.

It's due to include schools, sporting clubs, Irish dancing groups, and musicians.

Ballycastle businesses have been creating window displays in advance of the parade which Ms Goodlad said adds to the carnival atmosphere for the community.

The parade is due to leave from the Dalriada lower carpark at 13:00 GMT.

"Everyone will be gathering in their club or community club colours … from there we'll all walk together behind the lovely piper," she said.

"There will be lots of ribbon waving and we hope that once we get to the seafront the stage will be ready to go with live music from local acts."

Paula Reid, who is also on the event's steering group, said: "There will be something for everyone.

"I was inundated with lots of people coming to me asking if they could participate. It has been phenomenal."

Ms Reid said they have had a "great response and great support from local businesses and the general community. Everybody is so looking forward to it".
