I am very much hampered in writing about  our building project in Burlington Gardens, owing to the blanket ban on the posting of any photographs in order to maximise the impact of the public opening which is on Saturday 19th. May.   But having been round two and a half times today, it’s getting on.   Sydney Smirke’s vaulted undercroft under the main floor galleries is particularly amazing with a cast of the Farnese Hercules installed where the goods lift used to be.   Architectural casts are being hung in the Dorfman Architecture Court outside the lecture theatre.   And the Thornhill copies of Raphael’s Cartoons are being touched up before three of them are hung in the Collections Gallery.   Oh, and the Laocoön has appeared, too.
