Pope Francis is "disappointed" he is not visiting Northern Ireland when he travels to the Republic of Ireland in August, Archbishop Diarmuid Martin has said.
Details of the Pope's visit to Ireland were announced on Monday, June 11.
It was hoped he would travel to Northern Ireland as part of the visit, however it was confirmed on by the Vatican that the Pope will not cross the border.
Asked if he is disappointed by this, Archbishop Diarmuid Martin said: "Of course there is disappointment.
"We were hoping this was going to be the opportunity (to visit Northern Ireland). But the pressure of this event has overtaken that."
He added that the Pope has not ruled out the opportunity to visit Northern Ireland on a separate trip.
He is scheduled to visit Dublin on August 25 and 26, when the city hosts the World Meeting of Families, and will meet President Michael D Higgins as well as visit St Mary's Pro-Cathedral.
The pontiff will also pay a visit to Knock shrine in Co Mayo and celebrate mass in Phoenix Park.
