As part of the programme for the restyling of the Rome underground, based on the new identity and image sought in the Manzoni station project, the project for the Colosseum station demonstrates the desire to create a space in which contemporary materials, steel and Corian, frame large panels in which the existing mosaics are placed. The materials used characterise an environment in which the red band that identifies the Atac brand becomes a fundamental symbol of the new corporate brand.
