Glastonbury Festival and Worthy Farm have gone hand in hand since 1970.
But for the first time its founder Michael Eavis has hinted the venue could change in 2018.
Every five years organisers take a fallow year to let the ground recover, but Eavis says he has "something special planned" for the next one in two years time.
"I am getting old and don't want to miss out on any festivals," he told the Bristol Post.
Eavis, who celebrated his 80th birthday last year, said: "I am very proud of what we have managed to achieve over the years.
"I wake up every morning and get excited just thinking about the festival."
The Olympics were happening in London the last time the festival didn't happen in 2012.
This summer the festival is happening during the European referendum, with the organiser Emily Eavis encouraging people to vote by post.
Eavis leaves a lot of the organising to his daughter, and doesn't want to fully retire yet.
"At my age I want to enjoy as many festivals as I possibly can.
"We have the biggest act in the world with Adele on Saturday night and on the Sunday night we have the biggest band in the world.
"When I celebrated my birthday in October Chris Martin came over from the States for the celebrations."
Coldplay, Muse and Adele are some of the headliners who have been announced. It's thought 2018 could take the festival out of Somerset.
