The Wimbledon Centre Court roof in numbers

The annual Wimbledon Championships are now under way at the All England Club in south-west London, where almost half a million fans will enjoy a fortnight’s feast of tennis. For the last six years, Centre Court crowds have been spared long, frustrating rain delays thanks to the stadium’s impressive retractable roof.

First used in 2009, the structure is a feat of engineering that we can certainly appreciate here at Gibbons, so take a look at these seven fascinating facts about the Centre Court roof:

  • Costing an estimated £80 – 100 million, the 56,000 square foot roof weighs 3,000 tonnes and stands 16 metres above the court surface.
  • The roof takes up to 10 minutes to close, controlled by variable-speed drives to ensure it moves at no more than 214 mm per second.
  • Programmable logic controllers (PLCs) constantly monitor the roof’s movement to ensure its position remains within a tolerance of 1 – 3 mm.
  • Play can be suspended for as long as 45 minutes while the stadium’s air conditioning system acclimatises. This is to prevent condensation forming on the roof and playing surface.
  • Nine chiller units are required to cool the air.
  • Once the roof is closed, the air-management system provides 143,000 litres of conditioned air per second in order to keep the temperature between 22 and 26°C, with 40 – 60% relative humidity.
  • The roof contains 120 lights to allow play to continue up to 11pm.
