Running the length of the facility’s roof and down the front face to the entryway is an illuminated work of art that marks the location of the vault from a distance. In Norway, government-funded construction projects exceeding a certain cost must include artwork. KORO, the Norwegian State agency overseeing art in public spaces, engaged the artist Dyveke Sanne to install lighting that highlights the importance and qualities of Arctic light. The roof and vault entrance are filled with highly reflective stainless steel, mirrors, and prisms. The installation reflects polar light in the summer months, while in the winter, a network of 200 fibre-optic cables gives the piece a muted greenish-turquoise and white light.
