Opened October 2021, Casson Mann’s light-filled design for the new Holocaust Galleries at Imperial War Museums London sets a new precedent for presentations of the subject. Galleries suffused with colour reinforce the shocking fact that the Holocaust was planned and carried out in ‘plain sight’ – in the centre of civilised Europe. Authentic objects play an emotive role, as enduring witnesses to historic events. Displays include photos, original films, diaries, drawings and letters, as well as personal objects ranging from jewellery and clothing to toys and keepsakes. Every design detail, including light, sound, materials and colour, has been carefully selected to support evidence and facilitate better understanding of the Holocaust.
