Saturday’s Champions League final between Cristiano Ronaldo’s Real Madrid and Gianluigi Buffon’s Juventus will take place amid taut security following last week’s fatal terror attack in Manchester.
The suicide attack at Manchester Arena, which left 22 dead and scores injured, means vigilance will be heightened, but unprecedented security measures were already in place for the game.
Most noticeably, the retractable roof of the Principality Stadium will be closed, making it the first Champions League final to be played in indoor conditions.
The FAW said security was the “primary factor” in the decision to close the roof, although there is no evidence of a security threat against the final.
Fans will not be allowed to bring bags into the stadium, which will have a reduced capacity of 66,000 for the match, and have been encouraged to use left-luggage facilities in the city centre.
They have also been urged to arrive no later than two hours before kick-off to allow time for security checks.
Around 1,500 police officers are due to be on duty in the Welsh capital over the weekend, with local units supported by specialist officers from other areas of the United Kingdom.
As the Principality Stadium sits slap-bang in the centre of Cardiff, there will be road closures in place around the city centre on the day of the match.
There will also be tight security around the four-day ‘UEFA Champions Festival’, which takes place on the picturesque seafront at Cardiff Bay and is expected to attract over 200,000 people.
Events include a match between retired greats on Friday, due to take place on a floating pitch, and a DJ set by former Valencia and Barcelona midfielder Gaizka Mendieta on Saturday.
