In American football it's called 10 yards long patch of grass between the goal line and the end line end zone.
The goal of the offense is to go with the ball in the end zone of the opponent. In the four corners of the end zone pylons are colored to facilitate the arbitrators to decide whether a player is inside or outside the end zone. The Goal Line, which separates the end zone from the field is 20 cm thick drawn, while the other boundary lines are only 10 cm thick. Behind the endzone is the goal.
