This grand imperial staircase was the first of its type in Dublin and was created in 1749. Its generous architectural form created a suitably imposing first impression of the State Apartments. During the social season, debutantes and members of the aristocracy ascended this staircase in court dress on their way to attend balls, dinners and presentation ceremonies given by the Viceroy. Since 1938, it has been part of the main ceremonial route used during the inauguration of the President of Ireland in the State Apartments.
