This unique museum, 32 steps up a spiral stairway in the tower of St Thomas Church (1703), is the unlikely home of Britain's oldest operating theatre. Rediscovered in 1956, the garret was used by the apothecary of St Thomas’s Hospital to store medicinal herbs. The museum looks back at the horror of 19th-century medicine – all pre-ether, pre-chloroform and pre-antiseptic.
You can browse the natural remedies, including snail water for venereal disease and bladderwrack for goitre and tuberculosis. A fiendish array of amputation knives and blades is a presage to operating conditions at the times: surgeons had to be snappy; one minute for an amputation was judged about right. A box of sawdust beneath the table caught the blood, and contemporary accounts record the surgeons wearing frock coats 'stiff with pus and blood'. There are Speed Surgery demonstrations every Saturday at 2pm (reserve ahead, it can get busy) for a taste of Victorian brevity in its operating techniques. Demonstrations of herbal medicine are also given on Sundays. National Trust members get a 50% discount on admission.
