Margaret Court Arena is a tennis venue located in Melbourne, Australia. The capacity of the arena is 6,000 and was built in 1988. It was formerly known as Show Court One, but was renamed on the eve of the 2003 Australian Open to honor the Australian tennis great Margaret Court, who won more Grand Slam titles than any other player in history, male or female. It is the largest capacity fully outdoor court used at the Australian Open Tennis. Future improvements to the Arena include a capacity expansion of 1500 seats, to total 7500, as well as the installation of a retractable roof for the 2015 Australian Open.
