The Anatomy Tower is a ruined round tower and part of the remains of the city wall of Jena. It was the southwestern corner of the medieval city limits, is located at the Teich and Leutragraben and in the immediate vicinity of the Anatomical Institute and the Collegium Jenense.
The remaining section is the base with few windows. An anatomical theater with windows many meters high was built on top of it. Sloping toward the center, rows of wooden benches surrounded the mortuary table. Preparatory demonstrations took place here for medical teaching and scientific purposes, especially for medical students. On the one hand, the anatomy tower provided good exposure to the body donor thanks to the high windows, and on the other hand, it maintained discretion due to the location of the anatomical theater a few meters high and the lecture hall-like slope.
In the anatomy tower, Johann Wolfgang Goethe and Justus Christian Loder researched the premaxillary bone of the human embryo and the elephant. However, the premaxillary bone was already known to the scientific world, so Goethe and Loder's research - contrary to their mistaken opinion - did not represent a new discovery.
