Telekom Center Athens, also dubbed T-Center Athens, and previously known as OAKA Basketball Arena, is part of the Spyros Louis Olympic Athletic Center of Athens (Greek: O.A.K.A. «Σπύρος Λούης»). It was completed in 1994 and is the largest indoor venue in Greece. It was used for sporting events at the 2004 Summer Olympics. The venue is located in Marousi, a northern suburb of Athens. During its construction, it was considered to be one of the biggest and most modern indoor sports arenas in all of Europe.
The 18,300-capacity arena is accompanied by an adjacent training facility, and a parking lot.
In 2023, Panathinaikos B.C. signed an agreement with the Greek state for a 49-year concession of the asset, making the club the sole tenant and binding it to invest in the renovation of the asset's infrastructure. The club has since transferred the responsibility of managing the venue to White Veil S.A., a company which specializes in venue and facilities management, and is also owned by Dimitris Giannakopoulos.
In August 2025, a 5-year deal between White Veil S.A. and Cosmote Telekom S.A. (a subsidiary of Deutsche Telekom A.G.) was officially announced, for the rebranding of the entire venue as Telekom Center Athens.
