The Thursford Christmas Spectacular has delayed its 2020 show until next year, meaning the production will not take place for the first time in more than four decades.
The event, which employs more than 350 performers and production staff and is one of the biggest Christmas shows in Europe, will be replaced this year by a promenade immersive experience and light display.
Founder, producer and director John Cushing said the decision to cancel the planned production had been "heartbreaking".
"We have watched and waited, hoping for news and direction as to the implications for mass gatherings and live performances, which, in these uncertain times, remain unclarified at this time," he said.
It comes as pantomime producers and theatre figures warn that the government must publish dates within the next two weeks, detailing when theatres will be able to reopen, if the majority of Christmas shows are able to go ahead this year.
Cushing said that having considered the necessary restrictions and safety measures, "we felt that our only option was to postpone the show for this year".
It will be the first time that the Christmas Spectacular has not taken place at Thursford, in Norfolk, since it was first staged in 1977.
In its place this year will be The Enchanted Journey of Light, described as "an immersive experience of light and sound" comprising indoor and outdoor displays.
Cushing added: " Christmas is a special time of hope, joy, sharing and caring, and after a year filled with uncertainty and loss it is more important than ever that we celebrate all that we are thankful for. We look forward to seeing Christmas Spectacular audiences return in 2021 and hope that many will also visit our Enchanted Journey of Light this year.”
