The Dutch delta is a reclamation landscape. It has undergone several transformations since the Middle Ages to become an inhabitable, beautiful and unique cultural landscape. Many factors that determine the spatial quality of the future urban landscape are directly connected with the formal properties of the polder landscape of the Dutch lowlands. The form of a landscape is no accidental or random phenomenon, but the result of a transformational process that can also be called a formal process when seen in terms of form. Knowledge and understanding of the basic forms are instrumental in the design of the new landscape.
