Königsberg City Archive

The Königsberg City Archive (German: Stadtarchiv Königsberg) was the municipal archive of Königsberg, Germany.

The towns of Altstadt, Kneiphof, and Löbenicht were united to form the city of Königsberg in 1724. The city's archives were subsequently located in Altstadt Town Hall, but moved to the original campus of the University of Königsberg in Kneiphof in 1911/12. It was subsequently destroyed by the 1944 bombing of Königsberg and the 1945 Battle of Königsberg.
