From Platform 9¾ in Harry Potter to Bill and Ted’s phone booth, a new exhibition about portals explores the ways we’ll soon be moving around the metaverse

With its hidden doors, folding walls and clever optical tricks with mirrors and light-wells, Sir John Soane’s Museum feels like just the kind of place you might stumble across a portal to another dimension. Moving from one room to the next in this wildly reimagined London townhouse is never as straightforward as stepping through a simple doorway. The eponymous neoclassical architect and collector saw to it that the thresholds between the different parts of his house-museum were elaborate spaces in themselves, topped with lanterns and lined with mirrors and windows, offering views up, down and through his multi-levelled maze of antique treasures.Step through one opening, expecting another stately drawing room, and you find yourself standing on a bridge, suspended in a three-storey “sepulchral chamber”, where a glazed dome brings light down to an Egyptian sarcophagus in the basement. Pull back the folding panels in the picture room, and you discover a statue of a nymph in a hidden recess, floating above a void that plunges into another sculpture-encrusted nook below the floor. Each carefully choreographed transition, each theatrical reveal, is designed to transport the visitor to a parallel universe, whether it be the ancient ruins of Giambattista Piranesi’s Paestum, the demonic halls of John Milton’s Pandemonium, or the drawings of imaginary cities made up of fragments of Soane’s own buildings.
