Please see below notice from Croke Park:

July 20th, 2017 | Club notes

Following a review of safety procedures with the relevant statutory authorities, Croke Park can confirm that as of Sunday, 25 June 2017, patrons will not be permitted to take large bags and backpacks into the stadium for all match day and concert events.

Smaller bags (no bigger than A4 – 8.27in/21cm × 11.7/ 29.7cm) will be permitted but may be subject to searches and patrons are urged not to bring bags at all where possible.

Please allow plenty of time to get into the stadium, and for match entry procedures, ticket checks and searches, we would advise arriving at the stadium at least 1 hour before throw-in.

We would like to thank our patrons in advance for their cooperation with this matter as we look forward to a fantastic season of concerts and matches in Croke Park over the coming months.
