Benjamin Britten's monumental anti-war oratorio from the Vladislav Hall of Prague Castle in memory of war veterans and victims. British composer Benjamin Britten wrote War Requiem in 1962 on the occasion of the restoration of the war-damaged cathedral in Coventry. He used the traditional, codified Latin text of the requiem – a mass for the dead – interspersed with verses by Wilfred Owen, a British officer who wrote his poems directly in the trenches of World War I. More than two hundred artists then joined their voices in the Vladislav Hall of Prague Castle as part of the Prague Sounds festival for a symbolic performance of the work, which is rarely performed due to its demanding nature and large cast.
