In discussing Somerset House yesterday, I remembered that we have a chimneypiece by Joseph Wilton which came from the original Council Room in Somerset House and was moved to the new Council Room in Burlington House, after the Royal Academy had moved in 1868.   But they had left Somerset House in 1837, so it was quite a feat to have transferred the (very elaborate) chimneypiece, presumably with the permission of the new occupants of the rooms in Somerset House:-

Wilton was an intriguing figure – well known and successful as a sculptor, trained in Flanders and Paris, knowledgeable about antiquities, and one of the four key figures in the foundation of the Royal Academy, but, at the same time, running a successful yard, selling chimneypieces from Queen Anne Street East, opposite Marylebone Fields, sellings casts, urns and vases by the yard.
