The Stryperdijk is a wierdijk; an earthen dike that is covered with large sea grass on the sea side. Seagrass forms a hard mass under pressure and was therefore used for dike construction. The Stryperdijk has broken through several times. In front of the Stryperdijk was a large piece of land outside the dike. That was diked in 1603. This is how the Polder het Nieuwland, which is also called the Stryperpolder, was created. Later, the summer dyke was replaced there by a heavier winter dyke. But because this dike also broke through regularly, the polder was relinquished to the sea in 1688. The Nieuwland then became a salt marsh again. The churchwardens of East Terschelling then rented out the area as pasture. In order to preserve this cultural-historical heritage for the future, the Stryperdijk was transferred in 2013 by Wetterskip Fryslân to the Waterschapserfgoed Foundation. In that year the profile of the Stryperdijk was also restored in a few places and a tableau of different forms of stone revetment was laid out at this location. An information panel has also been placed explaining the history of the polder dike and the different types of stone revetment. The panel was unveiled on Friday afternoon 9 May 2014 by chairman Pieter de Haan of the cultural-historical association 'Skylge myn Lântse', chairman Bertus Mulder of the Waterschapserfgoed Foundation and dike warden Paul van Erkelens of Wetterskip Fryslân.
