From the Story
"The Quidditch pitch is where all the house Quidditch games take place. It is in front of Hogwarts, across from the Forbidden Forest. The seats are raised high enough so that spectators can watch the game. At either end stand three golden goalposts, fifty feet high each."Quidditch is a wizard sport, which is played high in the air on broomsticks. Each team has seven players, consisting of three Chasers, one Keeper, two Beaters, and a Seeker. The Chasers score by throwing the red Quaffle through the opposing team’s goalposts, guarded by the rival Keeper. Players must also avoid Bludgers, black balls that are struck at them with bats by Beaters. The game ends when one team’s Seeker catches the Golden Snitch – a small, winged ball – earning the team one hundred and fifty additional points. The team with the most points wins.
