K.B. Hallen is named after Københavns Boldklub, Copenhagen's first ball-playing club, which was established in 1876. It is used primarily for handball, badminton and tennis, but also hosts other events, including dance tournaments and flea markets.
As a concert hall, K.B. Hallen holds a capacity of 3,000 persons, and is often the scene of rock and pop concerts. (Wikipedia)
