Through Chalk

On 29 May 2007, close to the cliff tops, the GeoCenter Møns Klint was opened by Queen Margrethe. The museum was designed by PLH Architects, the winners of an international design competition.

On 13 July 2025, Møns Klint was one of the items accepted for inclusion on UNESCO's World Heritage List.

Geology

The chalk forming the cliffs consists of the remains of shells from millions of microscopic creatures (coccolithophores) which lived on the seabed over 70 million years ago. As a result of huge pressure from glaciers moving west, the terrain was compacted and pushed upwards, forming a number of hills and folds. When the ice melted at the end of the last ice age about 11,000 years ago, the cliffs emerged. They form part of the same deposits as the cliffs of Rügen, Germany, on the other side of the Baltic. Today, it is possible to find fossils of various types of shellfish as the sea continues to erode the chalk. Erosion also caused one of the highest points on the cliffs, the "Sommerspiret", to fall into the sea in 1998, and in January 2007, there was an even larger landslide around the Store Taler, in the northern part of the cliffs, creating a 300-m long peninsula of chalk and fallen trees stretching out into the sea below.
