A fortified encampment was built on a point of land called Lyngs Odde, near the current location of Fredericia, with a rampart stretching to either side of the point, thus protecting the encampment from attacks.

However, the fortifications were not perfect, and when Swedish Field Marshal Lennart Torstenson invaded Jutland, he was able to break through the ramparts.

On 15 December 1650, the King signed the document giving the town its first privileges, and work on the new fortifications could begin.

Every 6 July, the town of Fredericia holds a festival to commemorate the 1849 Battle of Fredericia, fought during the First War of Schleswig, in which Danish troops won a victory over the Schleswig-Holstein rebels who were laying siege to the town.
