The first pictures have been released of Devonshire Green's huge 46m screen for the England v Croatia game.
Around 6,000 fans are expected to pack into the fan park to watch the crucial World Cup clash tonight.
The Lord Mayor of Sheffield, Magid Magid, promised a 'massive screen' on Devonshire Green after England beat Sweden in the Quarter Finals.
He tweeted: "With Sheffield being the true home of football and England absolutely bossing it in the World Cup, we will be putting on a mahoosive screen on Dev Green from 6pm on Wednesday 11 July! Let's all have party!"
The fan zone will open today at 5.30pm for the 7pm kick-off and will stay open until 9.30pm - longer if extra time and penalties are needed.
Sheffield Council has installed a 46m screen to show all the action from Moscow and have said they are expecting around 6,000 fans to attend.
The council has said there will be zero tolerance to any glass on site and plastic glasses will be provided where possible but people should provide their own plastic glasses where possible.
To assist with this, and in agreement with local bar owners, the council has agreed that there will be one bar as part of the event on Devonshire Green to help reduce people leaving the site and carrying drinks between locations.
In addition local bars will be encouraged to play their part in the event but must use plastic glasses.
The Forum will also be used as a bar although it’s not in the arena.
People attending the event will be encouraged to bring their own food and drink or use local businesses or make a night of it and use local bars, restaurants, shops and cafes.
