40,000-Capacity Arena A venue steeped in culture and traditions The beautiful 40,000-seat Al Thumama Stadium is inspired by the gahfiya, a cap worn to hold men’s traditional headdress in place, as well as on its own by boys. The arena’s emotive design tugs at the heartstrings of Qataris and people across the region. More importantly, its cultural role marks every young boy’s path to into adulthood.
