If you're in London and are interested in the history of medicine, then once you're done with this museum you might want to checkout the Wellcome Collection.<p><a href="https://wellcomecollection.org/visit-us" rel="nofollow">https://wellcomecollection.org/visit-us</a><p>It's a free museum. I went into it randomly when I was out exploring, and it was pretty interesting (and I don't have any particular interest in the topic)
