Plans for a 1916 Rising exhibition and visitor centre for the GPO have been approved by Dublin City council.
An post intends to build the two storey centre in a courtyard currently not accessible to the public behind the main hall of the O'Connell Street building.
The development, which is expected to cost around 5 million euro, will involve the construction of a raised courtyard deck with an exhibition area, a gallery space below, a cafe and outdoor landscaping.
However the council has refused permission for a shaded walkway.
The proposed works are not within the historic portion of the GPO and would be confined to the 20th century complex, with the entrance to the exhibition area through the main hall.
