Bellevue Teatret functions as a garden in the sense described by Mark Pimlott: a public interior that reinterprets and stages the exterior. Designed by Arne Jacobsen in the 1930s as part of a broader commission in a seaside district near Copenhagen, the theatre blends functionalist principles with a sensitivity to place. The retractable roof is not just a technical innovation, it transforms the space into a hybrid between indoor theatre and open-air stage. Through it, light, wind, birdsong, and the smell of the sea enter the building, allowing nature to become part of the performance. This permeability reflects the garden’s essence: a place of encounter, open to the ordinary and the exceptional. The two corner foyers, used both as lobbies and exhibition spaces, support this flexibility. They extend the theatre’s function beyond scripted performance, opening it to informal gatherings and visual culture. Jacobsen’s attention to human scale and atmosphere further supports the idea of the theatre as a garden. Despite the building’s size, warm materials such as bamboo, wood, and fabric create intimacy. The blue and beige tones echo the sand and sea, while soft lighting and carefully designed furniture, like the wave-like accumulation of his own chairs, domesticate the monumental. These details invite comfort, wandering, and collective experience.
