This year's (15) festival was thrown into jeopardy when builders unearthed an ancient roundhouse, believed to date back several thousand years, at the site of the music event at Strathallan Castle in Perthshire, Scotland.

Preparations for the outdoor extravaganza, which will host bands including The Libertines, Kasabian and Noel Gallagher's High Flying Birds next month (Jul15), were put on hold and an archaeologist was called in to examine the find.

Fans had feared the discovery would prevent organisers from hosting the festival on the site, but the experts have now given them the green light to go ahead with the event.

A spokesman for T In The Park tells British newspaper the Daily Record, "Work has started again and the discovery won't affect site preparations."

The festival previously faced an uncertain future after rare birds were spotted at the site earlier this year (15).
