The Athens Olympic Tennis Centre is a grouping of 16 tennis courts at the Athens Olympic Sports Complex, in Marousi, Athens, Greece. The centre consists of a main stadium, known as The Main Court, seating 8,600 fans - though only 6,000 seats were made publicly available during the 2004 Summer Olympics - two semifinal courts, seating 4,300 spectators - though only 3,200 seats were made publicly available during the Olympics - and thirteen side courts, seating 200 observers each.
Each of the courts use the DecoTurf cushioned acrylic surface, the same surface as the U.S. Open Grand Slam event. The Main Court, in particular, is extremely large by the standards of major tennis competitions, with the seats being relatively far removed from the tennis court.
