A very small free museum but very interesting exhibition about the discovery and early years of penicillin. The volunteers are friendly and welcoming. There are a couple of souvenirs available in the shop, which is cash only. It is also up several flights of stairs with no lift.

The Alexandre Fleming Museum is a small but really special place. It tells the story of a doctor and scientist whose work changed the world, in a way that feels personal and easy to connect with. Being located inside a real, working hospital makes the experience even more powerful-you can truly feel the link between his discoveries and everyday medical care. It’s a quiet, thoughtful visit that leaves you with a lot of admiration for both the man and his legacy.

Friendly volunteers. You have to ring the bell and they will buzz you in. You can see the actual room where Penicillin was discovered! A must visit for anyone with an interest in Biology, Mycology, Bacteriology, Science, since this was a discovery of great historical value

It’s worth persisting at the entrance to wait for a response to the bell. The focus of course is on the discovery and research done at this site and not on the considerable work to turn that into a reality. It’s great that in an area of such pressure for space that the museum remains. The discovery must’ve led to the saving of many millions of lives. The museum is small and spread over several floors, but well worth visiting (it’s free).
