Green tide leads to Rome for St Patrick's Day greening
The Colosseum in Rome and the Sacre Coeur church in Paris are among 120 landmark sites going green for St Patrick's Day.
A host of iconic buildings and natural attractions will be illuminated in green on March 17, Tourism Ireland announced,
Some 60 major global sites have already confirmed they will take part in the greening project and another 60 are expected to be added to the list shortly.
Tourism chiefs are jubilant that the Colosseum - one of the world's most famous buildings - will be involved in the greening process for the first time.
Other newcomers to the list include Nelson's column in London; Jumeirah Etihad Towers Hotel in Abu Dhabi; the townhalls of Munich and Bamberg; and the Christ the King statue in Lisbon.
The Grand Ole Opry house in Nashville - home to the show that made country music - will also go green for the first time, as will Porte de Bourgogne in Bordeaux and the Fram polar exploration ship in Oslo.
The idea for greening buildings had started in earnest in 2010 with the Sydney Opera House which proved the inspiration for rolling it out all over the world.
Tourism Minister Paschal Donohoe said that it was hugely helpful to tourism as it generated enormous media coverage and reminded people of Ireland at a time when they were planning their holidays.
The aim was to boost visitor numbers by 6pc and revenues by 7pc after an excellent year in 2014, he said. "When we achieve those objectives that will bring the number of visitors in and out of our country to an incredible eight million this year," he said.
