The rotunda of the former psychiatric clinic harbors one of the city’s most fascinating and, at the same time, most bizarre secrets. Inside the Narrenturm, you’ll find the Pathological-Anatomical Collection of the Vienna Natural History Museum —a globally unique exhibition on the history of medicine, diseases, and human anatomy. Built in 1784 under Emperor Joseph II as the world’s first psychiatric clinic, the rotunda now serves as a setting for historical specimens, wax models (moulages), and medical instruments. Whether you’re a curious visitor, a science enthusiast, or a fan of the macabre: here you’ll get an up-close look at the darker side of anatomy.
A look behind the walls of the “Imperial Gupf”

The five-story rotunda is an architectural marvel even from the outside. But the true magic unfolds inside the Narrenturm. In the former patient cells, you’ll journey through centuries of medical history. The collection impressively demonstrates how doctors used to diagnose illnesses, which diseases shaped Vienna, and how the art of healing has evolved to this day.
Moulages and Masterpieces of Medicine
The extremely detailed moulages are particularly fascinating. These lifelike wax casts were once used to train medical professionals and depict clinical conditions with astonishing precision.You’ll walk past historical skeletons, medical devices, and preserved organs that bring history to life.
