Waterford and Tipperary are set to play key roles in the visit by Prince Charles and his wife Camilla to Ireland later this month.
Prince Charles will visit Ireland from March 23-25 as part of the global spring tour by members of the British royal family.
The heir to the British throne last visited Ireland in 2019 when he met with President Michael D Higgins in Wicklow.
That visit was the fifth by the Prince of Wales to Ireland in the space of five years - with the Republic assuming major importance on recent royal itineraries.
Famously, Prince Charles is a close friend of the Duke of Devonshire and travelled to stay with him at Lismore Castle in west Waterford in March 2004 for the 60th birthday of the Duke who was then known as Lord Hartington.
Lismore and its estate remains one of the key properties owned by the Duke of Devonshire and the Cavendish family.
The prince was accompanied on that 2004 trip by Camilla Parker-Bowles and the couple went hillwalking near The Vee amid tight security.
Prince Charles and Camilla married the following year in a civil ceremony at Windsor.
Last month, Queen Elizabeth II said she wants Camilla to be styled Queen Consort when her son assumes the throne - a move taken as a major show of support for Prince Charles and the role Camilla has played over recent years within the royal family.
Queen Elizabeth II also visited Dublin, Kildare, Tipperary and Cork in an historic Royal visit in May 2011.
While details of where the royal couple will tour in March have not yet been confirmed, it has emerged that Waterford and Tipperary are expected to play a key role in the programme though Prince Charles is also expected to visit Dublin.
Full details of the prince's itinerary will be announced later this week but Waterford, Lismore, Cashel and Cahir have been linked with potential Royal stopovers.
Major security inspections have taken place around parts of Waterford city centre, Cashel and Cahir over recent weeks by the Garda special protection team and members of the British royal security unit.
The Viking Triangle - a sensitively developed part of Waterford city centre that dates back to when the Vikings founded Waterford as Ireland's first city - is expected to form part of the royal tour according to WLRFM.
The area features a number of museums and is also close to both Waterford City Hall, Waterford's Church of Ireland cathedral and the new headquarters of Waterford Crystal.
It is unclear whether Prince Charles will again include Lismore on his Irish itinerary.
Lismore Castle has famous connections to royalty and celebrities with Prince John, Sir Walter Raleigh, Fred Astaire, John F Kennedy, Lucian Freud, John Betjeman and Cecil Beaton all having stayed at the keep overlooking the River Blackwater.
Other members of the Royal family will also be undertaking a series of worldwide tours this spring though Queen Elizabeth II - who was treated for Covid-19 last month - will remain in the UK.
A series of special events have been organised to mark Queen Elizabeth’s role as Britain's longest reigning monarch.
