gm. Młodzieszyn, pow. sochaczewski, woj. mazowieckie

The village was settled by the Dutch colonists probably at the beginning of the 19th century (in the section later called in SGKP Uderz Mały). In 1892, Uderz Duży had 140 residents and 133 morga of land, while Uderz Mały - 39 residents and 53 morga of land.

The linear section of village of Uderz is located on the western side of the Iłów-Kamion road along an east-west line, while its multi-street section on the eastern side of the road along a north-south line.

The cultural landscape of the village situated on the western side of the village is well preserved. The homesteads are located on the northern side of a dirt road by the marshy area with drainage canals on its northern side. Numerous poplar and willow trees, planted along the field balks are visible. A traditional Dutch homestead has survived next to the road.

An object without a number is a masonry building, erected ca. 1920. It is located on the northern side of the road along an east-west line as part of a single-building homestead, which is surrounded by a picket fence. The building is made of pine wood and has two types of structure: a corner-notched log structure (residential section and cowshed), joined at corners by dovetail halvings with log ends and a timber frame structure, which is reinforced with horizontal beams and planked with vertical boards (barn). The building has a double-pitched, rafter-collar beam roof covered with roofing paper. The residential section has a two-bay and two-axial interior with a centrally located chimney and a tile kitchen stove. The cowshed has one room; the single-threshing floor barn also functions as a shed. The building is preserved in good condition.
