Peristeri's home arena, the 4,000 capacity Peristeri Indoor Hall, opened up in 1989. By the early 1990s, the sport of basketball had become well established in Greece, and the Greek Basket League had become the strongest professional national domestic league in Europe, as well as the richest. A rising number of television viewers in Greece were watching the league, there was a high level of Greek media interest in the sport, and the application of the country to host major sports events had left many of the nation's existing gyms too old and too small for the times. So, in Athens, the Nikos Galis Olympic Indoor Hall was opened in 1995. It holds 19,250 spectators (21,098 standing room capacity), and it is still one of the two biggest indoor sports halls in Europe, where regular basketball games are held. The Nikos Galis Olympic Indoor Hall has hosted the 1995 FIBA Under-19 World Cup, the 1995 EuroBasket, the 1998 FIBA World Cup, and the 2004 Summer Olympics. Currently, the men's club Panathinaikos plays its home games in the Olympic Hall. the men's sections of AEK Athens and Maroussi have also played home games there.
