Dougie's Tavern in Hebburn, South Tyneside, has been transformed into a sea of national flags representing each team competing in the tournament.
As teams are knocked out, their flag will be taken down.
It has grabbed a lot of attention so far, and the pub is using that attention to raise money for the charity Rainbow Trust, placing buckets on the doors.
With crowds expected at venues like Dougie's Tavern, South Tyneside's Director of Public Health Tom Hall says people need to celebrate safely, as concerns over the Delta variant rumble on.
"The main concern is that those restrictions still stand and we really need to see them being complied with. Over the weekend and into next week, especially as we're dealing with a much larger number of cases as a result of the Delta variant that is spreading quite rapidly through various parts of the country and now very much in the North East as well."
It has been recommended that chanting, cheering, and singing should be kept to a minimum as projection can lead to a spread of the virus.A fan zone has opened on Newcastle's quayside today and organisers there say it will be a challenge keeping people quiet.

24 teams will compete for the trophy, currently held by 2016 winners Portugal, with England's campaign set to kick-off on Sunday (13 June) afternoon against Croatia at Wembley Stadium.
The first match of the tournament sees Turkey take on Italy in Rome tonight (11 June).
