Important elements of the contemporary cultural landscape of central part of Mazovia, especially its central and northern parts are remains of Dutch settlements, and in particular rural systems and remains of Dutch farms. Those farms were organized differently than in a typical farmstead Mazovia. Locating of farm buildings and roads connecting the various farms on upland terrain – natural or artificial frequently (called trep and trytfa) deserve on special attention. Those structure which were connected with colonies localized near the rivers are clearly visible even today. The langloff houses are very interesting and valuable. Those house combined several functions and that’s why were very magnificent and pointed out. A typical feature for Dutch farm was also the order of the gardens: orchard, vegetable gardens and ornamental gardens. Another element typical of Mennonite settlement was the use of trees as part of anti-flood damage. The rows of head-off willows (Salix alba and S. fragilis), sometimes poplars (Populus alba) are still well visible in all Mazovia. These plantings were accompanied by roads, bounds, drainage ditch. The fascines hurdles were very often used between individual trees in this row. These elements are still visible. However, as a result of uncontrolled spatial planning and garden fashions these elements are exposed to destruction. Dutch heritage is still very importaint in structures of Mazovian cultural landscape and that is why each element of this heritage deserves attention and protection.
