Tourism Ireland will unveil plans today for it's largest ever global St Patrick's Day celebrations.
Iconic landmarks and buildings around the world will go green for the eighth year in a row - and there will be some new additions.
Niall Gibbons, CEO of Tourism Ireland says we are going greener than ever: "We're delighted that we are going to see over 250 global icons go green around the world making it the biggest one yet.
"It has been a great success over the last number of years,
"Patrick's Day is a really important day in the Tourism calender.
"It's a great national holiday for Ireland but it is also a time where people are thinking about taking their summer holidays so it is a great time to be out in the media, a lovely positive time for Ireland."
