Celebrations to mark St Patrick's Day have taken place around the world - with over 500,000 people turning out for the parade in Dublin.
Over 3,000 performers took part in the parade itself - which had Irish football legend John Giles as Grand Marshall.
Dozens of other parades also took place in cities and towns across Ireland and the rest of the world. More than two million lined the streets for the 251st St Patrick's Day parade in New York.
Taoiseach Enda Kenny was guest of honour at the Chicago St Patrick's Day parade.
As part of the celebrations, 31 global landmarks turned green for the day, including the leaning tower of Pisa, Table Mountain, the London Eye, the Sydney Opera House and Burj al Arab in Dubai.
The 'Global Greening' was part of a Tourism Ireland initiative to promote the country abroad.

1843 UPDATE ON LEPRECHAUN STAND OFF: It seems a late surge from Bandon has left them a wee bit clear of Glenties in the race to gather the most leprechauns in one place
Bandon recorded 1,263 leprechauns, while Glenties were a little bit short with 1,024.
The pint-sized previous record of 414 was held by a school in South Africa.
Each town now has to submit its evidence to the Guinness Book of World Records for official confirmation.

Over 4,000 people lined the streets of Ennis in Co Clare for today's parade. Overall 51 groups from around the county took part in what was a fun and colourful family event with an international flavour. The theme of this year's parade was ‘Ennis: a town of many cultures.’

1520 North-West Correspondent Eileen Magnier has the latest on the leprechaun stand-off:
Two towns are trying to beat the Guinness Book of World Records for the biggest number of leprechauns in the one place as part of their St Patrick's Day celebrations today.
Glenties in Co Donegal and Bandon in Co Cork are both trying to beat the record currently held by a school in South Africa of 414 leprechauns.
Hundreds of people dressed as leprechauns are registering this afternoon in both towns and there seems no doubt that one or other will beat the record if their evidence is accepted by Guinness, which attaches strict criteria to the records - all the leprechauns must be wearing a green hat, green waistcoat, white shirt, black or green trousers and shoes with buckles.
The towns have independent judges present today, but have to send detailed visual and documentary evidence to support their claim to the record, and it will be approximately six weeks before they know if they are the new record holders.

1405 Cathy Halloran reports from Limerick:
An estimated 40,000 people lined the streets of Limerick city centre to view this year’s St Patrick’s Day parade.
The theme of this year’s parade is 'The World in Union', as the city celebrates its huge community base, its diversity and ethnicity, and the fact that St Patrick's Day is now a major celebration across the globe.
Over 4000 participants from almost 130 community, arts, cultural and sporting organisations took part.
There was music from a number of city bands, and plenty of dancing from groups representing countries as far apart as Latvia and the Philippines, as well as plenty of colour from inner city community groups and those involved in education and lifelong learning, as well as from the large number of sporting organisations spread throughout the city.
The Grand Marshall this year was Dr Ed Walsh, the founding President of the University of Limerick, to mark the university's 40th anniversary.
