Euro 2020 games in Copenhagen this summer can be played in front of crowds of at least 11,000, Denmark's culture minister Joy Mogensen said Thursday.
And should the coronavirus situation allow, more could be permitted to attend the four matches played in the capital's Parken Stadium, which has a capacity around 38,000.
"The football European Championships is a unique and historic event in Denmark," said Mogensen.
Danish football's governing DBU said it was a "big and important step" towards hosting a successful part of the pan-European championships which take place in 12 cities across the continent.
European football ruling body UEFA has asked countries to guarantee at least some fans will be able to attend matches. No city which cannot make this promise will be automatically removed, UEFA has said, but games could be switched to where fans are allowed.
Denmark will face Finland, Belgium and Russia in Group B games in Copenhagen, which also hosts a last 16 match in the June 11-July tournament.
Finland in St Petersburg
Russia's other two matches, and Finland v Belgium, will take place St Petersburg and will also have fans attend.
Alexey Sorokin of the local organizing committee told state news agency Ria Novosti an agreement had been reached to use 50% of the 68,000 capacity ground.
"We are looking to the Euros with optimism," he said and added foreign fans could even travel to Russia, which does not currently have a strict coronavirus lockdown in place.
"We are convinced that the central sporting event for Russia will be held with the minimum permissible restrictions and in compliance with all the necessary rules," he said.
