The rockslides occur with great force
Some changes occur suddenly and cause severe changes to the coastline. In 1905, one-third of Liselund Park, some 40,000 sqm slid into the sea, and great cultural values were lost. Sommerspiret, which was a favourite motif of the Danish painters of the early 19th century and which, for generations, had been regarded as the landmark of the cliff, disappeared in 1988. In 1994, a rockslide near Dronningestolen meant the loss of a French tourist’s life as she walked on the beach just as the cliff slid. One of the biggest slides in recent times occurred in 2007, when Store Taler with up to 500,000 cubic metres of chalk, clay and soil together with approximately 100 beech trees pounded 300 metres into the Baltic Sea.
Today, the Nature Agency manages approximately 540 hectares of forests, bogs and other nature areas at Høje Møn.
