Tisvilde

From around 1500, drifting sands began to bury the fields and farms around Tisvilde. The problem accelerated over the years and by 1700, most of the area had been deserted. 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. The first tree species to be planted was scots pine and later followed by spruce, birch, beech and oak. 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.[4] This area is a part of the Kongernes Nordsjælland National Park.[5] Some of the species protected here are northern crested newt and large white-faced darter.[6]

The coastline at Tisvilde Hegn is known for its stretches of white, clean and child-friendly sandy beaches.[7]

• Helene Spring is one of Denmark's most famous springs, and legend has it that anyone whose illness has not responded successfully to other forms of treatment must come to the spring on 23 June (Sankt Hans Eve or Midsummer's Eve). Culturally, legend in Denmark has it that if one consumes a certain amount of water from its springs in the night and then stays at Saint Helene's grave until morning, he should be cured of all his sicknesses.[8]

• Tibirke Church was built on the site of an ancient "vi", a pre-Christian holy place. At the foot of the church near Bækkebrovej is a spring which may have been the place where pilgrims came in days of old. The church was originally the center of a small village with 10 farms, but they were all (including Tibirke Church) buried by drifting sand dunes and abandoned by order of the King in 1725.[7][9]
• Helene's Tomb is now a rectangular, grazed area surrounded by low stone fences. The two boulders leaning against each other indicate Helene's Tomb. It is located at Sankt Helenevej, 3220 Tisvildeleje.[10]
• Wieth-Knudsen Observatory built in 1959, is located in southern part of the town. The observatory is offering astronomical meetings open to the public, twice each month throughout the year.[11]
