I got this online at Al-Arabiyah English:

Wanting to spark a buzz, Tourism Ireland has sealed a deal to bathe the world’s top tourist destinations in green to mark of Ireland’s national day.

“The reason we do it is to create a buzz and to spark interest, to celebrate the unique nature of what it means to be Irish. To make people smile and to make them think of Ireland around March 17,” Bernard McMullan, a spokesman for Tourism Ireland, told NBC News this week.

Wouldn’t the Western Wall look good in green?
