The Steinburg district and its district seat, Itzehoe, are located on the west coast of Schleswig-Holstein, approximately 60 kilometers north of Hamburg. This modern administrative region evolved from the Steinburg district, which was first mentioned in a document in 1307. The town of Itzehoe on the Stör River is a medieval settlement that was strategically located at the intersection of three trade routes and, thanks to the “Lübschen Rechte” granted to the new town, was attractive to merchants seeking to settle there.
The Joint Archive consists of two independent and separate archives: the Steinburg District Archive and the Itzehoe City Archive. They were housed together in a single location in 1983 and have been under full-time professional management since that time.
