[1] No location is specified in the constitution, but all inaugurations have taken place in Saint Patrick's Hall in the State Apartments in Dublin Castle.
The ceremony is transmitted live by national broadcaster RTÉ on its principal television and radio channels, typically from around 11 am.
To highlight the significance of the event, all key figures in the executive (the government of Ireland), the legislature (Oireachtas) and the judiciary attend, as do members of the diplomatic corps and other guests.
In the 1970s instead of separate denominational ceremonies a single ecumenical multi-faith service was held in the cathedral of the faith of the president-elect.
[3] For the first inauguration in 1938 President-elect Douglas Hyde wore a morning suit, with black silk top hat.
The president-elect (unless they are already a serving president, in which case they will already be living in the presidential residence) are usually driven to the inauguration from their private home.
