The stadium roof is toroidal (like a doughnut) in shape. It is suspended from steel cables attached to eight towers. These provide access to the upper level of seating via spiral ramps. The areas without seating in each corner have movable louvres. This allows for air to move through the pitch. Entry is gained by contactless smart card rather than the usual manned turnstile. This system can admit up to 1,200 people per minute around all entrances. A service tunnel running under the stadium provides access for emergency vehicles. It allows the visiting team's bus to enter the stadium directly. Inside the stadium are six themed restaurants. Two of restaurants have views of the pitch. There are also a number of conference facilities. The stadium is also licensed for marriage ceremonies.
