The O2 arena is one of the leading facilities in Europe with a capacity of up to 20,000. Every year, the O2 arena hosts dozens of attractive sporting and cultural events. It was opened in 2004 for the ice-hockey championship and since that time it has welcomed over 600,000 people every year.

The O2 arena is located in north-eastern Prague, approximately 10 km from the city centre. It occupies an advantageous position between the interior road ring, which provides comfortable transport from other sections of the city, and the external ring road, which allows a quick connection to the outgoing motorway and the international highway network.

The O2 arena offers more than fourty spatial, functional or technical variations of the stage surface and the auditorium. At a large rock concert, the O2 arena can host up to 20,000 spectators. The latest technology available at the O2 arena include, e.g., a giant video cube, internal TV circuit, display facades, its own TV studio, sliding stands, excellent acoustics, light park and advanced telecommunication equipment.

In addition to the standard auditorium, the O2 arena offers non public floors for skybox and club seat tenants. It also features business areas with necessary facilities, a number of lounges, restaurants and bars along with seminar facilities, press conference rooms and congress halls.

O2 arena is owned and operated by Bestsport, a.s., which is part of PPF Group. PPF invests into multiple market segments such as banking and financial services, telecommunications, biotechnology, real estate, insurance and agriculture. PPF's reach spans from Europe to Russia, the USA and across Asia. PPF Group owns assets of EUR 27 billion (as at 31 December 2016).
