Following last month's horrific Manchester Arena attack, concert venues across the world have been cracking down on security.
Croke Park is following suit, as Gardaí and MCD promotions have issued a warning before tonight's Coldplay gig.
First up, Gardai have advised that people allow extra time to get to Croke Park, as there will be full body and bag searches for everyone to gain entry.
An armed support unit will also be at the scene.
Inspector Tony Gallagher told The Irish Examiner that the Gardaí are well prepared.
'We've a very robust policing and traffic plan in relation to it and we've some 180 personnel working at the event.'
'We're there really to facilitate the enjoyment of this concert by the 82,000 fans,' he said.
Big bags, backpack, selfie sticks, and large umbrellas are also banned from the concert.
