The Freud Museum is always a good place to visit to soak up design tips from the master of psychoanalysis (specialism: couches) but it’s worth returning to for a look at the sculptural installation of Turner Prize-winning artist Mark Wallinger. In a piece titled ‘Self Reflection’, Wallinger has fixed a mirror across the ceiling of Freud’s study, offering a new perspective both on the room, and on the discipline of psychoanalysis itself.
