Opening Hours

The State Apartments dominate the south range of the Great Courtyard. They were built as the residential and public quarters of the Viceregal Court and were the seat of the executive and focus of fashionable and extravagant social life (an account of Viceregal Court life is given in Chapter 15 of the Dublin Castle History).

Today the Apartments are the venue for Ireland's Presidencies of the European Union, Presidential inaugurations and prestigious functions.

The Undercroft is sited at lower ground floor level in the Lower Castle Yard, opposite the Chapel Royal. The city walls join the Castle at this point. Here, the archway allowed small feeder boats to land provisions at the postern gate, from larger boats moored on the Liffey. The double archway and postern gate are still visible. Also on view here is the Viking defence bank, within the butt of the Norman Powder Tower. The original Tower was five stories high - the top storey being occupied by the Lord Deputy during the 16th century.
