Standard gridiron football field, with bleachers along the sidelines and two large goal posts standing at either end. The endzones are usually painted in the style of the two Houses competing that day.
An old green court adorned with a torn, old net. The white lines around the court are almost invisible and there is a tattered bench for spectators. Unfortunately the courts don't see much use, but the gates are left unlocked for those who care to play a game of tennis.
A raised wooden platform out in the center of the platform, wide and circular. The assistant to the Defense and Combat teacher creates mirages here, which allows students to spar in exotic locales without receiving any serious injuries.
