The Barbican Centre is a performing arts centre in the City of London and the largest of its kind in Europe.[1] The Centre hosts classical and contemporary music concerts, theatre performances, film screenings and art exhibitions. It also houses a library, three restaurants, and a conservatory.

The London Symphony Orchestra and the BBC Symphony Orchestra are based in the Centre's Concert Hall. In 2013, it once again became the London-based venue of the Royal Shakespeare Company following the company's departure in 2001.[2]

The Barbican Centre is owned, funded, and managed by the City of London Corporation, the third-largest artsfunder in the United Kingdom. It was built as The City's gift to the nation at a cost of £161 million (equivalent to £480 million in 2014) and was officially opened to the public by Queen Elizabeth II on 3 March 1982. The Barbican Centre is also known for its brutalist architecture
