The Gardai will be holding a National Centenary Commemorative Event in Dublin today.
The force is marking 100 years since the first Garda Commissioner Michael Staines marched into Dublin Castle for the handover of policing duties from the British.
There'll be a parade of over 400 gardai at the Gresham Hotel on O'Connell Street ahead of the event at Dublin Castle on Dame Street later this morning.
Superintendent Liam Geraghty says it's an important day for the Gardai:
"Today is a very special day for An Garda Síochána. In August 1922, the first Garda Commissioner Michael Staines led the then civil guards, about 450 members of the newly formed civic guards into Dublin Castle, taking over Dublin Castle from the Royal Irish Constabulary, who then ceased to exist. An Garda Síochána then became the only police force in An Garda Síochána and the police service for the newly formed state."
