OAKA — Athens' Olympic Hall and Panathinaikos' Lair
The Olympic Indoor Hall in Athens — universally known as OAKA, after the Olympic complex it anchors — opened in 1995 and was the basketball centrepiece of the 2004 Olympic Games. Today it's the home of Panathinaikos, one of the most decorated clubs in EuroLeague history, and on big European nights it produces an atmosphere that belongs on any list of basketball's great rooms.
Olympic bones
OAKA was built to Olympic scale: a vast roof span, seating around 18,000 for basketball, and the airy concourses of a Games venue rather than a club hall. The 2004 Olympics gave it iconic moments — including Argentina's golden run through the men's tournament — and the wider complex, crowned by Santiago Calatrava's white steel arcs over the main stadium, remains Athens' signature sports landscape.
The Greens
Panathinaikos turned the hall into a trophy factory. The club's EuroLeague titles — six by the mid-2010s, with more European silverware since — were built on legendary coaches (Željko Obradović won a record haul here) and rosters mixing NBA-bound talent with continental superstars. The club's Gate 13 ultras paint the bowl green with coordinated tifos, flares and ninety minutes of sustained noise; visiting NBA players who guest in EuroLeague games consistently rank it among the most hostile environments in the sport.
Derby of the eternal enemies
OAKA's biggest nights come against Olympiacos, the Piraeus rival whose own hall sits by the port. The Athens derby has been decided at Final Fours, marred by famous flare-outs and elevated by some of the best playoff series Europe has staged. It is, alongside Belgrade's derby, the reference point for how much a basketball game can feel like a volcano.
NBA pipeline
Panathinaikos and OAKA have hosted, formed or finished the careers of dozens of NBA names — both Americans finding a second peak in Europe and Greek stars heading the other way. The building is part of the standard answer to "where do NBA fans start with EuroLeague?"
Spotting it in basketbadle
OAKA's tells: an Olympic-scale roof with exposed white steel, surrounding parkland rather than downtown blocks, and — in interior shots — green everywhere, often with banner walls behind one basket. If the photo says "Olympic venue repurposed by a fanatical club", say OAKA.
