Harry and Meghan looked relaxed as they made their way down the steps and shook the hands of the waiting officials in turn, before being led to their car at the head of a motorcade.
Nearby nine Garda motorbike outriders were waiting to escort the couple to a meeting with Ireland’s Taoiseach Leo Varadkar, who will formally welcome the couple to his country.
As their car pulled away Harry, looking smart in a suit, shirt and tie, smiled at the ranks of journalists, photographers and cameramen capturing the moment, and waved at them.
The trip to Dublin is not the first time the duke and duchess have been away since their May 19 wedding, which fused tradition with modernity and diversity.
Harry and Meghan slipped away unnoticed for their honeymoon and the destination for the traditional break has remained under wraps for now.
