A place worth remembering
A small room with movable picture planes
Sir John Soane’s Museum says movable picture planes let the 13-by-12-foot Picture Room (about 4 by 3.7 metres) display 118 paintings. For some fragile works, the museum displays facsimiles while originals are protected from light or undergoing restoration.[1]
From herb garret to operating theatre
The Old Operating Theatre Museum occupies the roof-level garret of St Thomas’ Church in Southwark. During the 18th century, a hospital apothecary used it to dry medicinal plants. The museum dates its conversion into an operating theatre for women patients to 1822.[2]
Fans and electric cars underground
The Postal Museum dates pneumatic-railway trials to 1863: engine-powered fans moved mail carriages through a tunnel. Mail Rail was a different underground line; it opened in 1927 and carried letters in driverless electric cars until 2003.[3]
