150 iconic landmarks and sites around the world are "going green" today.
It's part of Tourism Ireland's 2015 Global Greening initiative, which celebrates Ireland and St. Patrick's Day.
This is the sixth year of the Global Greening initiative, and it's the biggest yet.
World famous landmarks including the Colosseum in Rome, Sacré Coeur basilica in Paris, Edinburgh Castle, the Grand Old Opry in Nashville and the Equator Sign and Line in Uganda will all be lit up in green.
Niagara Falls on both the Canadian and US sides of the border, the Las Vegas welcome sign and the Empire State building will also go green, as well as the Great Wall of China, the Christ the Redeemer Stautue in Rio, the Shard in London, the London Eye, Bruges Town Hall, Hotel Negresco in Nice and City Hall in Tblisi all joining in the Irish theme.
It's a major coup for Irish tourism, highlighting our national celebration for St Patrick's Day.
