Global Greening: Must-see snaps of the landmarks going green for St. Patrick's Day
190 shades of green
Tourism Ireland's Global Greening is up and running, and it's throwing a powerful spotlight on St. Patrick's Day.
The Empire State Building, Great Wall of China and Las Vegas's Welcome Sign are among some 190 global landmarks going green this year.
The Global Greening aims to throw a spotlight on Ireland as a holiday destination on a day when goodwill pours in all over the world.
This is a time "when many people are planning their holidays, giving Ireland an unparalleled platform to encourage people to pay us a visit," said Paschal Donohoe, Minister for Transport, Tourism and Sport.
Tourism Ireland estimates that its St. Patrick's Day promotional activities generate international publicity worth around €10 million, with near saturation coverage across print, broadcast and social media.
As of March 17, it estimated the cost of the 2016 initiative at "just under €29,000".
New participants this year are 7 World Trade Center in New York, the Big Wheel in Paris, the light rail system in Addis Ababa and City Hall in Tel Aviv.
Other new sites set to go green in 2016 include Bridgestone Arena in Nashville, Mount Ulriken TV mast in Bergen and the Hofbräuhaus in Munich.
The Boston Red Sox baseball team will also wear green on St Patrick’s Day.
It's not just global landmarks, either. Locals in Rudolstadt, in the 'Green Heart' of Germany, have engaged a professional lighting company to turn Heidecksburg Castle green for the day - complete with drone flyovers.
The 2016 Global Greening switches on in a week when the CSO confirmed visits to Ireland increased by 20.4pc last year.
Ireland saw a record 8.6 million visitors in 2015, with the government aiming to grow that figure to 10 million annual visitors by 2025.
