Norbreck Castle Hotel is a large seafront hotel on Queens Promenade, in the Norbreck area of Blackpool, Lancashire, England.
In the late 1970s, the hotel's disco became the venue for a number of concerts by punk rock, new wave and mod revival bands. Those who played there included the Angelic Upstarts, Penetration and the Purple Hearts. The venue also saw gigs by two bands before they became famous. Adam and the Ants performed there when they were still a punk rock band in March 1979, a performance which One Way System drummer Dave Brown, listed in his top five gigs. And on 15 March 1979, The Pretenders played one of their first ever gigs at the Norbreck. Rock bands starting their careers on tour included Iron Maiden, Def Leppard and the first solo appearance of Ozzy Osbourne after leaving Black Sabbath. The American band The Stray Cats, who had moderate chart success 1980/81, also played one of their first UK gigs here.
