From the flatter country west of Odense, Vissenbjerg is a noticeable change. We reached it while travelling east through Funen, after the stops around Aarup and before continuing towards Odense. During that part of the route we checked two possible stopping places in Vissenbjerg, one on Lille Roldvej and another on Søndersøvej, before continuing towards the motorway and Odense.

The motorway is very close to the town, and that is part of the modern Vissenbjerg experience, but the reason the place exists where it does is much older. Unlike many Danish towns that grew around a harbour or railway station, Vissenbjerg developed high on a remarkably uneven piece of central Funen.

The town stands at roughly 120 metres above sea level, unusually high by Danish standards. Immediately south of it the ground drops sharply through woods, ravines and a series of broad, flat-topped terraces. The landscape looks almost like an enormous staircase.

It was created during the final stages of the Ice Age. Melting glaciers left complicated deposits of clay, sand and gravel, while meltwater cut channels through them. The resulting Vissenbjerg Bakker are some of the most dramatic hills on Funen and one of the reasons this part of the island feels so different from the country around Odense.

One of the strangest formations is known simply as Afgrunden — “The Abyss”. Despite the dramatic name, it is not an enormous canyon, but it is impressive in Danish terms: the ravine is around 400 metres long and reaches about 16 metres deep. Walking through it makes the glacial origin of the area much easier to understand than looking at it from the road.

There are several marked walking routes through the hills, generally between about 2.5 and 4 kilometres. The highest viewpoints reach around 129 metres, with views across the central Funen landscape towards Frøbjerg Bavnehøj, the highest natural point on Funen.

Vissenbjerg has another history that is rather less scientific. For centuries the dense forests around the town were associated with robbers and outlaws.

There is some reality behind the stories. In medieval Denmark, people declared outside the protection of the law needed places where they could disappear, and the thick, difficult forests around Vissenbjerg provided exactly that. Travellers crossing Funen could avoid the area by taking the longer main route, but anyone in a hurry might risk the more direct road through Vissenbjerg Gyde.

That gave rise to generations of robber stories. Some are clearly folklore, but the reputation became strong enough to remain part of Vissenbjerg’s local identity long after the forests were opened up and the real danger disappeared. Large-scale clearance during the eighteenth century gradually made hiding more difficult, and by the nineteenth century the era of the Vissenbjerg robbers was effectively over.

The town itself also developed because people travelling across Funen needed somewhere to stop. A proper village began taking shape in the nineteenth century around the medieval church after a royally privileged inn opened. As travel between different parts of Denmark became more common, the inn and several shops turned Vissenbjerg into a roadside stopping place. Until the 1950s, development was still concentrated largely along the old A1 main road.

There is also much older human history here. The nearby Koelbjerg Man is one of Denmark’s most important prehistoric finds. The skeleton dates from roughly 10,500 years ago, shortly after the end of the Ice Age, and is among the oldest known human skeletons found in Denmark. A local museum explains both the find and the landscape in which these early inhabitants lived.

Next to the hills is something completely different: Terrariet Vissenbjerg, known for its collection of reptiles, amphibians and other exotic animals. Its animals include snakes, lizards, tortoises, frogs, scorpions and spiders, making it a surprisingly substantial attraction for such a small town.

Our two stops around Vissenbjerg were very much part of the practical side of crossing Funen. Lille Roldvej and Søndersøvej are close to the motorway corridor rather than being scenic motorhome destinations in their own right, and the road system makes it easy to continue east towards Odense. We did exactly that after working our way through the smaller towns west of the city.

But Vissenbjerg itself was more interesting than the motorway surroundings suggest. It sits on one of Funen’s highest pieces of land, surrounded by terrain left behind by melting ice, with a medieval road, old inns, prehistoric human remains and stories of robbers hiding in the woods.

It is one of those places where the landscape explains the history. The hills made travel difficult, the forests offered hiding places, the road created the town, and the modern motorway now passes almost beside it. What looks at first like an ordinary small Danish settlement is actually sitting on one of the most unusual pieces of terrain on the island.
