Telekom Center Athens: The Cathedral of Greek Basketball’s Golden Age
Nestled in Marousi, a northern suburb of Athens, the Telekom Center Athens stands as Europe’s most iconic basketball temple—a venue where history was made in 2004 and where the future of Greek basketball is being rewritten. With a capacity of 19,000 for basketball (the largest indoor arena in Greece), this glass-floored colossus has hosted Olympic glory, EuroLeague finals, and now serves as the centerpiece of Panathinaikos B.C.’s 49-year concession agreement with the Greek state.
But the story of Telekom Center isn’t just about numbers. It’s about a renaissance—a facility that has evolved from a 2004 Olympic relic into a cutting-edge sports hub, where every dribble echoes through the same halls that once witnessed Greece’s 2004 Olympic gold medal victory. With a €15–18 million renovation underway (completed in 2026), this isn’t just an arena. It’s the beating heart of Greek basketball.
The Birth of a Basketball Cathedral
Completed in 1994 as part of the Spyros Louis Olympic Athletic Center (O.A.K.A.), the venue was originally known as the OAKA Basketball Arena. Designed to be one of Europe’s most modern indoor sports complexes, it quickly became the spiritual home of Greek basketball, hosting the Greece men’s national team since its inauguration and welcoming Panathinaikos B.C. as its primary tenant.
Its claim to Olympic fame came in 2004, when it played host to basketball events at the Athens Summer Games, including Greece’s legendary gold medal win over Argentina. The arena’s glass floor—a signature architectural feature—became synonymous with the sport’s fluidity, a visual metaphor for the country’s basketball soul.
A 49-Year Lease and a €18 Million Makeover
In 2023, Panathinaikos B.C. Signed a historic 49-year concession agreement with the Greek state, transforming the venue’s operational model. The club, under the leadership of Dimitris Giannakopoulos (via his company White Veil S.A.), now holds exclusive rights to manage and renovate the facility—with a mandate to invest heavily in its infrastructure.
The most recent renovation, completed in early 2026, included:
- A new glass floor system (replacing the original Olympic-era design)
- Expanded luxury suites and VIP areas (now accounting for 10% of seating)
- State-of-the-art sound and lighting systems (compatible with EuroLeague broadcast standards)
- An upgraded adjacent training facility, now used by Panathinaikos’ NBA-level development squad
- Enhanced public transit access, including a dedicated metro stop (OAKA Station on Athens’ Line 3)
The renovation cost—estimated between €15–18 million—was funded through a mix of private investment and Greek government subsidies. The project was overseen by Decathlon S.A. (as lead architect) and Aktor Group S.A. (general contractor), with design feasibility studies conducted by Populous.
“This isn’t just an upgrade—it’s a rebirth. Telekom Center will be the model for how European clubs can partner with governments to modernize legacy venues.”
Who Calls Telekom Center Home?
While Panathinaikos B.C. is the primary tenant, the venue remains a national asset, hosting:
- Greece men’s national team (since 1995; used for EuroBasket and FIBA World Cup qualifiers)
- EuroLeague and FIBA EuroCup (regular-season games and playoffs)
- International concerts and events (e.g., Justin Bieber’s 2025 Athens tour)
- Corporate and diplomatic functions (hosted by the Greek Ministry of Tourism)
The adjacent training facility is now home to Panathinaikos’ NBA-level development program, where young Greek talents train alongside former NBA players like Georgios Printezis and Nick Calathes.
How Telekom Center Stacks Up Against Europe’s Elite
With a 19,000-seat capacity for basketball, Telekom Center ranks among Europe’s largest dedicated basketball venues, alongside:
| Venue | Capacity (Basketball) | Location | Primary Tenant |
|---|---|---|---|
| Wembley Arena | 12,500 | London, UK | London Lions (BBL) |
| Telekom Center Athens | 19,000 | Marousi, Greece | Panathinaikos B.C. |
| Palau Blaugrana | 7,585 | Barcelona, Spain | FC Barcelona (basketball) |
| Mercedes-Benz Arena | 16,300 | Berlin, Germany | ALBA Berlin |
Key distinction: Unlike multi-purpose arenas (e.g., Madison Square Garden or The O2 Arena), Telekom Center is exclusively dedicated to basketball and sports events, ensuring an unparalleled fan experience.
The Roar of Marousi: What It’s Like Inside
Attending a game at Telekom Center is more than watching basketball—it’s a cultural pilgrimage. Here’s what sets it apart:
- The “Glass Floor Effect”: The translucent court allows natural light to flood the arena, creating an almost surreal playing surface. Fans report an “open-air” feel, even on cloudy days.
- Panathinaikos’ “Green Wave”: The club’s ultra-famous organized fan section (seated in the north stand) creates a “La Ola” that ripples around the arena, often lasting 10+ minutes during crucial moments.
- Post-game rituals: Win or lose, Panathinaikos players and fans gather near the “Heroes’ Wall” (a tribute to Greek basketball legends like Dimitris Diamantidis and Tony Parker), where chants of “Panathinaikos! Panathinaikos!” echo until midnight.
Pro tip: Arrive 90 minutes early for the “Athens Basketball Experience” exhibit in the concourse, featuring memorabilia from Greece’s 2004 Olympic gold and Panathinaikos’ EuroLeague titles.
The Next Chapter: EuroLeague Ambitions and Beyond
With its renovation complete, Telekom Center is positioning itself as a cornerstone of Panathinaikos’ EuroLeague dominance. Key upcoming milestones:
- 2026–27 EuroLeague hub: The venue will host 4 home games for Panathinaikos in the regular season, including a potential Top 16 clash.
- Youth development: The training facility will expand to include a high-performance academy for Greek U18 and U20 national teams.
- International tournaments: Bids are underway to host the 2030 FIBA Basketball World Cup (Athens is a candidate city).
The long-term vision? To make Telekom Center a year-round destination, blending sports, entertainment, and tourism. “We’re not just renovating an arena,” says White Veil S.A.’s CEO. “We’re building a legacy.”
