Thousands of people are celebrating St Patrick's Weekend in Dublin today as pop acts including Darius, Picture House and Fifth Avenue take to the stage in Merrion Square for the Big Day Out.
Fairground rides, an inflatable wrestling ring and Paddyoke - Irish-style karaoke - are just a few of the attractions for the thousands of visitors making the most of the bank holiday weekend sunshine.
But while some are revelling, in towns and cities across Ireland organisers are working hard on last-minute preparations for tomorrow's St Patrick's Day parades.
Pop star Samantha Mumba is to be Grand Marshal at Dublin's event, which will set off on its city centre route at about noon.
Pageants and bands will march through Dame Street and O'Connell Street in what is set to be the biggest St Patrick's Day parade the capital has ever seen.
There will be 13 street theatre acts and 17 Irish and international bands among the 3,800 performers taking part.
Organisers expect more than half a million people to turn out for the event and have advised people to arrive early to secure their places along the route.
Extra rail services are being put on to cope with the extra people travelling into the city.
After the parade, St Stephen's Green will be the centre of attention for the giant Ceili Mor.
Across Ireland bands were preparing for parades - although for the first time a number have had to be cancelled because of high insurance costs.
