The Groninger Landscape wants to realize a mound across the dike near Noordpolderzijl. This hill outside the dikes offers the inhabitants of Groningen, but also the rest of the Netherlands, the opportunity to experience a mound. Without the safety of a dike, but trusting the idea that you are high enough to keep dry feet. More than 2500 years ago, the first mounds were built in Groningen. These structures have protected the Groninger population for centuries against water. The mounds lost their primary function when building dikes along the Wadden Sea, but fortunately many still remain. As a result, these residential hills became an important part of the cultural heritage of the province of Groningen. The realization of the relationship between mounds and the sea has also been lost. With the creation of an mound outside the dikes, the Groninger Landscape will return this awareness. The design for the new mound will be a recreational function. Recreants and birdwatchers can use the hill. A tower gives a good view of the Wadden Sea with its natural habitat. The tower refers to the former buildings and is also a landmark. At dusk, in the top of the tower begins a lamp to light, powered by solar energy, and is a beacon for the environment. Benches and picnic tables were placed in 3 recessed parts at the hill. Here is a sheltered view of the surrounding. The mound acts in summer as a large sunbathing and swimming area. A dike serves as a connection between mainland and hill. To create different sight lines for the visitor the dike is knotted designed.
