First National Bank Stadium or simply FNB Stadium, also known as Soccer City and The Calabash, is located in Nasrec, bordering the Soweto area of Johannesburg. The stadium is also known by its nickname "The Calabash" due to its resemblance to the African pot or gourd. The stadium has been officially known as FNB Stadium since it was opened in 1989. During the 2010 FIFA World Cup, as well as in the month before the tournament, the stadium was referred to as Soccer City. It was the site of Nelson Mandela's first speech in Johannesburg after his release from prison in 1990, and served as the venue for a memorial service to him on 10 December 2013.
