St Patrick's Day: What's happening in Northern Ireland?

Thousands of people are expected to gather in towns and cities across Northern Ireland over the coming days to celebrate St Patrick.

Belfast aims to promote a confident, inclusive city with an abundance of homegrown talent.

While in Londonderry, the city will be celebrating "light over darkness" as Spring approaches.

Police have warned of traffic disruption in many areas as parades and festivities are held.

In Downpatrick, it is hoped the day will help drive footfall into the town centre recently hit by flooding.

BBC News NI takes a look at some of what's on offer across Northern Ireland this year.

Saint Patrick, the patron saint of Ireland, is thought to have grown up in Britain in the 5th century AD, during Roman times and to have first come to Ireland as a kidnapped slave.

Once he was free, he became a priest and returned to the country as a missionary.

St Patrick is honoured by the largest Christian denominations in Ireland.

It is believed he used shamrocks to explain the idea of the Holy Trinity to pagans which is why the clover has become synonymous with St Patrick's Day celebrations.

Some other legends, such as the belief that St Patrick banished snakes from Ireland, have been proven false.

St Patrick's Day was originally celebrated as a religious feast to mark his work, but now the day highlights Irish history and culture. It is only marked as a national holiday in the Republic of Ireland and Northern Ireland, but many people around the world get involved in celebrations, even if they have no connection to the country.

Landmarks around the world, like Sydney Opera House and the Empire State Building, are lit up green - and the Chicago River is traditionally dyed green to mark the day.

An abundance of parades, street parties and céilis (traditional Irish social gatherings involving dancing and music) can also be expected, no matter the weather.

Belfast has been hosting events since the start of March, from Irish language events to live music, art and dancing.

The council is supporting events happening until the umbrella of Seachtain na Gaeilge - an international Irish language festival celebrating Irish language and culture

For the first time, a St Patrick's Music Weekend is running, which includes a three-day "trad trail" across city centre venues.

It begins on Friday and finishes on Sunday night.

City Hall is the starting point for the parade on Sunday, starting at 13:30 GMT.

"People, place and planet" is the theme this year.

Lord Mayor of Belfast Ryan Murphy, said he wanted to celebrate Belfast's creativity and diversity.

"This year's St Patrick's Day programme really reflects that concept, with something for everyone to come along and enjoy," he said.

The parade will follow a circular route - Chichester Street, Victoria Street, High Street, Castle Place and Donegall Place - before making its way back to City Hall.

A festival village in Cathedral Gardens, next to St Anne's Cathedral, will host free performances, food stalls, céilí workshops and family-friendly activities after the parade.
