History of US Quidditch. Quidditch was founded in 2005 at Middlebury College by then-freshman Xander Manshel. Looking for a variation on their normal Sunday activities, Manshel and his friends laid the foundation for a game that has grown in leaps and bounds to become a widely respected, physically intense sport.
A Quidditch pitch is typically in the shape of an oval, five hundred feet long and a hundred and eighty feet wide, with a small central circle of approximately two feet in diameter. At each end there are three hooped Goal posts of different heights, surrounded by a scoring area.
