The Corps of Fortification

​

In its most original form, the Swedish Corps of Fortifications was founded as an independent entity in 1635 and it forms a predecessor to the engineering regiments. The Corps was primarily responsible for building and maintaining the country's permanent fortifications. It consisted of a corps of specially trained officers assisted by soldiers, mainly from the infantry regiments.  

The head of the agency was normally also the person in charge of the country's permanent fortifications. Miliseum's "Engineering Hall" begins with an exhibition concerned with the history of fortifications in Sweden. One of its central aspects is an exhibition about Jönköping Castle.
