Detail of the arch. The new 6,350 tonne roof covers an area of over 45,000 square metres (11 acres), 4 acres (16,000 m2) of which are movable and rise to 52 m (170 ft) above the pitch.[2] With a span of 317 m (1040 ft), the arch is the longest single span roof structure in the world and is 134 m (440 ft) above the level of the external concourse,[20] and is designed not to cast a shadow on the pitch.[27] Contrary to popular belief, the stadium's roof is not fully retractable, meaning it cannot cover the playing surface in inclement weather.[28] In theory, the roof is more of an umbrella against the rain for spectators and designed to avoid a shadow across the pitch rather than a fully retractable roof which can cover the entire pitch. Apparently there are concerns within FIFA that the pitch will never be of a standard to hold a World Cup Final. The present England manager Capello has made representations to the English FA complaining that the pitch hinders skillful ball playing.
