Went to La Specola the other week... it is Florence's Natural History Museum established in 1775. Dedicated to Zoology and anatomical waxes, studies of the brain and workings of the human body. It has a greatly artistic influence, a good blend of art and science. As well, there is a fantastic little book store. It's a great place to come and draw and get "close to nature" in a Memento Mori sort of way.
However, this Museum, like a lot of museums in Florence, is not getting the right funding to keep up maintenance.
