Sir John Soane's Museum is staring ruin in the face with its forthcoming exhibition. After its excursion into modernism with the highly successful Gehry exhibition, it is plunging back into romanticism with an exhibition called 'Visions of Ruin - architectural fantasies and designs for garden follies', opening on 2 July. This both harks back to Soane himself, who created a mock-ruin in the garden at Lincoln's Inn Fields, and looks at contemporary follies, including one by Terry Nichoson at the new Museum of Natural Phenomena in Orlando, Florida, which is intended to resemble a historic colonial mansion, dropped upside down on top of a brick warehouse by a hurricane. Sadly some of the most exotic but ephemeral follies ever created will not be represented - the blancmanges in the shape of Roman ruins concocted by Parisian chef Antoine Careme. That would be a feast for the eyes.
