Retractable roof
"The design of Al Khor incorporates a 93 m x 120 m retractable roof with a folding mechanism similar to the famous Wimbledon tennis court. The roof opens to let in direct sunlight onto the natural grass of the pitch. It can withstand rain storms and a full wind load. Furthermore, the roof does not inhibit outdoor air conditioning."
