The Cavern club is today celebrating the fiftieth anniversary of the first appearance of The Beatles on 9 February 1961.
 
In 2007 the Cavern celebrated its 50th birthday with a 13 hour party. The Beatles played hundreds of gigs at the Cavern Club between 1961 and 1963. The original club was located in the cellars of an old Victorian warehouse which was demolished in 1973 to allow a shaft to be built for the Mersey underground railway Link improvement. In 1983 it was decided that the Cavern should be rebuilt, following the death of John Lennon, a few yards away from its original location, reusing some of the old bricks reclaimed from the original demolition. Over 15,000 secondhand bricks from the old Cavern were reused in the reconstruction. Some salvaged bricks were taken by locals and 5,000 were sold by site owners the Royal Life company in 1983 for £7 each. A plaque certifying their authenticity was glued to each antique brick with the proceeds being donated to a local charity. All of the reclaimed bricks were sold, and in the late 1980s one Cavern brick was said to have been resold for over £500 by Sotheby's.
