Gardaí are warning people that protests ahead or during the Queen's visit will only be tolerated up to a point.
It comes ahead of a planned protest later at the Garden of Remembrance in Dublin, one of the historical sites the Queen is due to visit on Tuesday.
Socialist republican group Eirigi says it plans on setting up a "freedom camp" at the site from this afternoon until Tuesday.
Superintendent John Gilligan from the Garda Press Office said that gardaí will be monitoring the situation closely.
"If people want to come out and, for whatever reason, protest in relation to the visit, that will also be facilitated within reason, in terms of a reasonable protest will be allowed, a peaceful protest, but up to a point," he said.
"Gardaí are prepared, if necessary, to deal with any issues that arise."
