Also home of the Philadelphia Eagles, it was the first National Football League stadium to use artificial turf. In 2006, Gillette Stadium, the football stadium of the New England Patriots and the New England Revolution, switched from grass to artificial grass due to the conflict of poor weather and hosting many sporting and musical events at the stadium.
It is one of 13 National Football League stadiums that have turf instead of grass fields; the Patriots, Giants and Jets (who share a stadium) and Bengals actually switched from AstroTurf to natural grass before reverting to a next-generation artificial surface.
All eight stadiums in the Canadian Football League currently use artificial turf, due to that country’s northern climate.
