Dublin is likely to be given a major publicity boost when Britain's Prince Harry and his new wife Meghan Markle visit Ireland in July.
The couple will stay in Dublin for two days on July 10 and 11 for what has been described as a 'mini-moon'.
It will be Harry's first visit to Ireland while the Duchess of Sussex has been here before in 2014.
Sources say the couple are likely to pay a visit to Trinity College and may meet President Michael D Higgins at Áras an Uachtaráin.
A visit to the Guinness Storehouse is also being planned.
They are understood to be looking forward to learning more about Ireland's history and culture as well as meeting people who will shape the country's future.
It will be the second royal visit to Ireland this summer after Prince Charles and his wife Camilla visited Cork and Kerry last week.
Harry and Megan will follow their Dublin visit with an offiical honeymoon.
Commenting on the tourism potential of the visit to Ireland next month by the Duke and Duchess of Sussex, Niall Gibbons, CEO of Tourism Ireland, said: “The visit by the Duke and Duchess of Sussex will be a wonderful opportunity to showcase Dublin and Ireland to a huge audience of prospective holidaymakers across Britain and has the potential to deliver a major boost to Irish tourism.
“We expect a large media contingent will travel to Ireland to cover the visit, bringing the story to millions of people in Britain, and elsewhere around the world, and providing a truly unique opportunity to highlight Ireland as a wonderful holiday destination. Tourism Ireland will take every opportunity to exploit the tourism potential from the extensive publicity around the visit.
“Great Britain is an important market for tourism to the island of Ireland. It delivers 47% of all overseas visitors and around 28% of all overseas tourism revenue. Tourism Ireland is undertaking an extensive programme of promotions throughout 2018, to highlight Ireland to British travellers.
