When the Glastonbury Festival is not being staged, the frame of its Pyramid Stage is one of the few signs that Worthy Farm in Somerset, is anything other than an ordinary dairy farm.

The farm has been in the Eavis family for 154 years. The current owner, Michael Eavis, 72, was born in nearby Pilton and moved to the farm when he was eight.

The farmhouse is shielded from view when the festival is on. One of the festival litter bins, a recycled and painted oil drum, can be seen outside the front door.

One of the farm buildings hides a swimming pool where Mr Eavis does 24 lengths in cold water before breakfast every morning - even on Christmas Day.

The farm has 360 milking cows, which produce 10,200 litres per day - or 28 litres per cow. It is also home to 200 calves.

This tangled pile of metal is tent pegs that were left behind by campers at last year's festival. Mr Eavis wants to introduce biodegradable tent pegs that will not harm his cows.

Piles of abandoned Wellington boots also sit in skips on the site after being lost or discarded after last year's event, which turned into a mudbath after heavy rain.

The Pyramid stage frame is the one permanent festival structure. The stage has had several transformations since the original Pyramid was built on a ley line in 1971.

The stage will be covered at the start of May, when work on the site starts in earnest - almost two months before the event begins on 27 June.

Some 175,000 fans, media and crew will descend on the fields - turning them from empty green pastures into parts of a teeming city full of people, tents, stalls and, possibly, mud.
