Congenital malformations, diseased skeletons and animal skeletons

The collection of professors of anatomy Gerardus Vrolik (1755-1859) and his son Willem Vrolik (1801-1863) was purchased by the city of Amsterdam in 1869 and eventually found its home at the Academic Medical Center (AMC), one of the largest hospitals of the Netherlands, in the most south-eastern part of the city.

Other anatomical collections have been added to the museum over the years. There are also a number of animal specimens in the collection.


Museum Vrolik's collection includes about 10,000 anatomical specimens of humans and animals, such as skeletons and skulls, but also pathological anatomy and congenital malformations, such as dwarfism, cyclopia and Siamese twins in formaldehyde.

They are the result of severe developmental defects; so severe that the children died shortly after birth.


The collection can be visited by anyone, but it is most commonly used for education and research by the Faculty of Medicine students of the University of Amsterdam.

Parts of the Museum Vrolik collection can also be seen at NEMO science center.

Museum Vrolik also offers guided tours  but you have to request them at least 2 weeks in advance.

Not for young kids

The museum is more suitable for children of at least secondary-school age than for children of primary-school age.


The museum is located on the ground floor of the Faculty of Medicine (building J) of the AMC in Amsterdam Zuidoost.

The museum can be reached easily by public transport. Take metro 54 to Gein from Centraal Station and get off at Holendrecht.
