Fredericia is home to Northern Europe’s largest and most well-preserved ramparts. There are bastions, moats, canons, traverses and cavaliers. The Ramparts were constructed in 1650 by local farmers, soldiers and convicts. One of the most significant victories in Danish military history occurred here – the siege of Fredericia, on 6th July 1849. The Danish assault commenced in the dark of night, out through the portals, driving the Schleswig-Holstein forces away. The ramparts are today a beautiful and natural site.
