After the Second World War, there was a new beginning for the Institute, now named the Königstuhl State Observatory (LSW). In 1983 the Mannheim instruments were donated to the State Museum of Technology and Industry in Mannheim, where some of them now form part of the permanent exhibition. The 1859 six-stage telescope was given to the city of Karlsruhe in 1957 for the establishment of the Public Astronomical Observatory of Karlsruhe, another instrument was given to the National Astronomical Observatory Heppenheim. The valuable book collection of the old library, the oldest of which dates back to 1476, was transferred to the Manuscript Department of the University Library.
