Halden is Østfold’s border sentinel — a municipality where fortress walls overlook fjords, canals climb hillsides, and Viking ships sleep beneath farmland. With around 31,000 residents and a landscape shaped by rivers, forests, and centuries of conflict, Halden is the kind of place where you can explore baroque theaters, hike ancient pilgrimage trails, and still catch an opera in a mountaintop citadel. It’s got cannons, canals, and a name that once meant “slope.”
