King's currently operates two museums: Gordon Museum of Pathology and Museum of Life Sciences. Opened in 1905 at Guy's Campus, the Gordon Museum is the largest medical museum in the United Kingdom, and houses a collection of approximately 8000 pathological specimens, artefacts, models and paintings, including Astley Cooper's specimens and Sir Joseph Lister's antiseptic spray. The Museum of Life Sciences was founded in 2009 adjacent to the Gordon Museum, and it houses historic biological and pharmaceutical collections from the constituent colleges of the modern King's College London.
