Hat hills on Langeland
Discover Langeland's unique hat hills – created during the last ice age

On Langeland, long straight rows of low, round hills define the island’s landscape. In fact, Langeland is the only part of Denmark where you can see this type of landscape so clearly.They are known as “hat hills” or “hat-shaped hills” and there are over 1,000 of them. They were all created by a glacier that decided to park itself right here.
Hat hills
Langeland’s landscape was created during the last Ice Age by a glacier which moved over eastern Denmark around 17,000 years ago (an episode known as the Belthav Readvance).The hat hills sit in eight to ten parallel rows, that run f rom the north to the south. This can be most clearly seen in the middle of the island. The rows follow the orientation of the glacial margins. This leads geologists to believe they were formed in connection with the edge of the glacier. However, they are still not completely certain of the exact processes involved.
Hat hills can look very different depending on if they have trees growing on them, and if so, where they are growing. Trees growing on the top of a hill will emphasize its rounded shape, while trees growing around its base will make the shape more difficult to see. Many of the hat hills on the northern half of Langeland are covered in trees, which means the hats hills cannot be seen as clearly as they can on the southern part of the island.
Some hat hills next to the coast have been ero-ded by wave action. This allows you to see their internal structure and their unique sedimentary stratification.
