TRAIN stations, castles and major monuments across the county will join iconic buildings worldwide in going green for St Patrick's Day next year.
Tourism Minister Leo Varadkar is writing to all major state bodies asking them to pick Irish landmarks that could turn green for the year of The Gathering.
Mr Varadkar will write to county and city councils, government departments and the Office of Public Works (OPW) asking them to draw up lists of prominent buildings that could follow suit.
Next year's Gathering has been organised by Mr Varadkar's department and is aimed at getting the Irish diaspora around the world to return here for a visit, boosting the tourism industry in turn.
The 'greening' of domestic landmarks would link in with major sites internationally.
But the idea of Irish buildings taking part was only floated by Limerick Fine Gael TD Patrick O'Donovan last year.
"It's only right that public buildings and landmarks across Ireland should join in the greening," said Mr Varadkar.
"I'm calling on local authorities, public institutions and businesses to rise to the challenge. If the rest of the world can go green, then so should we," he said.
"Obvious landmarks include Leinster House and Government Buildings and Bank of Ireland on College Green and Liberty Hall, the Customs House, and the Wellington Monument in Dublin.
"Public buildings across Ireland should join in, with town halls being an obvious choice."
