The public is being warned to expect traffic disruption in Dublin this week, as the Irish capital hosts two major European Union presidency events on Thursday and Friday.
The Republic of Ireland has been chairing the EU presidency since 1 July and will continue to do so until 31 December.
This has led to Ireland being the meeting place for many political leaders from across the EU in recent months.
The two main showpieces of the EU presidency will be a meeting of the European Political Community (EPC) on Thursday 12 November and an informal meeting of the European Council the following day.
Some 50 international leaders will attend a meeting of the EPC, while leaders from the 27 EU member states, as well as some other international leaders, will remain in Dublin for Friday's meeting.
The EPC will take place in the Convention Centre Dublin, with a formal dinner in the National Gallery of Ireland on Thursday evening.
The informal European Council meeting will take place in the convention centre on Friday.
Arrivals and departures for these events will take place at Dublin Airport and Casement Aerodrome.
The security operation for the two meetings will be the largest in the state's history, according to An Garda Síochána (Irish police).
Supt Liam Geraghty said there had been "intense and extensive planning" between the force and local authorities, transport companies as well as businesses and residents in key locations.
"Our appeal is to advise the public of the significant traffic disruptions that will take place in order to put that policing and security operation in place," he said.
He described the policing and security operation as being bigger than those put on for any US presidential visit.
Where will the disruptions be?
The policing operation will begin and increase incrementally from Tuesday 10 November and Wednesday.
Gardaí expect to put in place temporary traffic restrictions across the wider Dublin region to facilitate security motorcycle escorts from Dublin Airport and Casement Aerodrome to Dublin city centre.
