Tennis polo
The sport is played on a grass field between 80 and 100 yards long and 50 to 65 yards wide. The goal area is a semicircular line with an 11-yard radius and the penalty mark at 13 yards from the goal. An experimental rule has a second semicircular line on the field with a 17-yard radius. Generally, a field for gridiron football or soccer can be used.
Stade de France
Located at 11 meters below the court, the playing area measures 9,000 square meters (120 meters long and 75 meters wide) to a grassed area of 11,000 square meters. Nearly one billion seeds were sown to produce the first pitch in 1997. Today, the grass comes in rolls of 1.20 mx 8 m. Changing the pitch calls for three days of preparation and five days of installation. The change takes place several times a year, depending on the programming stage.
Unlike many other stadiums, the Stade de France was built without under pitch heating, as the stadium was constructed on the site of an old gasworks, and there were concerns it could cause an explosion.
