The László Papp Budapest Sports Arena (Hungarian: Papp László Budapest Sportaréna), also known as Budapest Sports Arena or locally just Arena, is a multi-purpose indoor arena in Budapest, Hungary. It is the second biggest sports complex in the country after MVM Dome, which is also in the capital, and it is named after Hungarian boxer László Papp. The venue can hold up to 12,500 people in its largest concert configuration, up to 11,390 for boxing and 9,479 for ice hockey. It was built as a replacement for the Budapest Sports Hall (Hungarian: Budapest Sportcsarnok, or BS for short) which stood in the same place and was destroyed in a fire in December 1999. A long-distance bus station is situated under the building.

Construction of the arena began on 30 June 2001, after the original, the Budapest Sportcsarnok, built in 1982, burnt to the ground on 15 December 1999. The hall was finished quickly, within a year and a half, and the opening ceremony was held on 13 March 2003. Since 28 May 2004, the arena wears the name of Hungarian boxing great László Papp and is officially known as Papp László Budapest Sports Arena.^[1]

The building has a total weight of 200,000 tons and contains 50,000 tons of concrete, 2,300 tons of steel structure, more than 11,000,000 bolts and several kilometres of cable.^[1]

The state-of-the-art multifunctional plaza is capable of hosting almost any sort of sporting or civic event, such as basketball, gymnastics, ice skating and ice hockey, and other athletics events. It can also host extreme or thrilling events like monster trucks, motocross, jet-skiing or indoor wave surfing competitions.^[2] The arena also is the top venue in the area for touring international musicians and performers, as well as dance recitals, operas, dramas, circuses, musicals and a variety of other special events.^[2]

The building is protected by several fire safety systems. One of these is the protection alarm system, which in the event of a fire gives off the alarm within three seconds. The Budapest Sports Arena is also equipped with a fire hydrant system that, in the case of a catastrophe, can be used at more than sixty positions in the building. Every point of the arena can be reached with the help of the fire hoses. As a unique feature in Hungary, the building also contains three high-output water cannons. All three are positioned in the auditorium protecting the area that caused the destruction of the arena's predecessor. The Arena also has numerous fire doors that automatically lock in the case of a fire, so preventing the further spreading of a fire.
