Oxegen is an annual music festival held since 2004, sponsored by Heineken and is Ireland's biggest festival. The event is promoted by MCD. Oxegen was originally a two-day festival but for 2008 was increased to four days. It takes place at the Punchestown Racecourse in County Kildare, Ireland and has an average attendance of around 80,000 a day, with around 70,000 of these camping on site for the duration, and the rest travelling to the site each day. It takes place on the same weekend as T in the Park in Scotland and shares a very similar line-up each year, although Oxegen is generally regarded as Ireland's version of the world-renowned Glastonbury Festival, with the 2008 festival sharing three of the same headliners. The festival has attracted attention from outside Ireland, with many of those there travelling from overseas.
