Niagara Falls will gleam with green on March 17.

Tourism Ireland announced that the falls will go green in honor of St. Patrick’s Day in an effort to promote Ireland tourism. It’s part of the agency’s “greening” of landmarks, now in its third year, the Irish Times reports.

In recent years, landmarks that have been “greened” include: the London Eye, the Empire State Building in New York, Burj Al Arab in Dubai, Table Mountain in Cape Town, the CN Tower in Toronto, the Sydney Opera House, the Sky Tower in Auckland, Battersea Power Station in London, Nelson Monument in Edinburgh, the Manneken Pis in Brussels, the Puerta de Alcalá in Madrid and the Moulin Rouge in Paris.

“Our aim is to bring a smile to the world and to convey the message that Ireland continues to offer a warm welcome, fun and spontaneity, alongside fantastic scenery and cultural activities,” Tourism Ireland’s chief executive Niall Gibbons said in a statement.

Last year, Tourism Ireland sponsored the wildly popular Irish dance flashmob that today boasts more than 2 million hits on YouTube. The flashmob—organized by my friends, Chris Naish and Jason Oremus of the Sneaky Steppers!—was one of these most popular viral videos of 2011. With help from more than 100 Irish dancers from local dance academies and a touring Riverdance troupe, the Sneaky Steppers treated travelers at Sydney, Australia’s Central Station with the ultimate St. Patrick’s Day performance.
