St Mary’s Hospital is home to the Alexander Fleming Laboratory Museum where Fleming discovered the antibiotic penicillin at in 1928. It was a breakthrough that revolutionised medicine and earned him a Nobel Prize.

Amongst the science and experiments are exhibits about Fleming himself and his realisation and commitment to the further development of his discoveries. Visitors to the museum are taken back to a time without antibiotics, when the smallest infection could lead to death.

A recreation of the experiment that Fleming accidentally contaminated and from which the antibacterial powers of Penicillin were discovered is also on show. The museum also chronicles Fleming’s development of the drug and its use in modern medicine.

In 1999, the museum was declared an International Historic Chemical Landmark by the American Chemical Society and the Royal Society of Chemistry, and received a San Marino Idea Award for penicillin as one of the five greatest advances of the 20th century.

In 2000 it received an award from The Times for penicillin as a national millennium treasure.
