The Duke and Duchess of Cambridge will visit the North tomorrow.
William and Catherine are attending a garden party at the Royal residence at Hillsborough Castle, Co Down.
The North's secretary of state has hosted the event annually since 1984.
Around 2,500 guests have been invited by Theresa Villiers this year, with attendees drawn from a wide cross-section of the North’s society, including the voluntary and community sectors, local charities and youth organisations.
The occasion will be only the second time the Royal couple have visited the North together.
The last time was in March 2011, only weeks before their wedding.
On that occasion Catherine tossed pan cakes at Belfast City Hall and hammered in fence posts at Greenmount Agriculture College in Co Antrim.
