Amsterdam is a city of museums – there are more than 400 museums and art galleries within the city. It is said that no other city in the world has more museums than Amsterdam. Obviously, museums are among the main tourist attractions. The Rijksmuseum, Van Gogh Museum, Anne Frank House and the Stedelijk Museum are the most popular choices, but there are many interesting smaller museums. There are museums on coffee, spectacles, pianos, diamonds, cheese, beers, bags and purses that we featured earlier, and many more. Here are the most bizarre ones.

Museum Vrolik houses a tremendous collection of pathological specimens, anomalous embryos, odd skulls and bones, and other anatomical abnormalities, put together by the Gerardus Vrolik (1755-1859), one of the most important Dutch scientist of its times. Willem Vrolik was a pioneer in the field of teratology - the study of deformities - a popular subject for anatomists in the 18th and 19th centuries. Willem published several monographs on teratological subjects and amassed thousands of specimen.

After the death of Willem Vrolik, the collection was purchased by a group of Dutch citizens and offered to the municipality of Amsterdam to be placed in an institution called Athenaeum Illustre, which became later University of Amsterdam. Today, the Museum Vrolik includes specimens from other collections, added through more than a century of its existence.
