Tisvilde is a small town with a population of 1,385 (1 January 2024) [1] located on the north coast of the island Zealand (Sjælland) in Denmark 60 km (37 mi) in Gribskov Municipality, northeast of Hillerød.

Several attempts to counter the forces of nature, had been tried, but in 1724 the German Johan Ulrich Røhl was hired by the Crown and by help of the local peasants and 100 soldiers from Copenhagen, they managed to stop the dunes in the course of the 1730s, by covering them with seaweed and digging trenches.

But while the dunes was successfully stopped in their march against civilisation, the sands had covered and transformed the countryside and made it completely barren.

From around 1800 to 1900 this state was reversed, by planting the c. 1,300 ha forest[3] of Tisvilde Hegn in association with the plantations of Asserbo and Liseleje southwest.

Tisvilde Hegn is the oldest plantation in Denmark[3] and now a Natura 2000 area, due to its rare habitat-types, flora and fauna and important birdlife.
