History of Regnellianum
The Dag Hammarskjöld Library and Law Library is located on the corner of Trädgårdsgatan and Slottsgränd, adjacent to Östgöta Nation.
The building was constructed in 1891–92 following a donation from Anders Fredrik Regnell, a physician, and was previously named Regnellianum. In 1877, he was appointed doctor honoris causa (honorary doctor) at the Uppsala University jubilee party.
The building was utilised by Uppsala University until 1968, serving as the offices of the Departments of Physiology and Pathology.
In 1981–1982, a major reconstruction was conducted to better meet the requirements of the Department of Theology.
At the dawn of the 21st century, the Department of Theology left the premises, and the building was let as a commercial office.
The Dag Hammarskjöld and Law Library is a listed building in Sweden, meaning that it is legally protected due to its historical significance.
