gm. Czosnów, pow. nowodworski, woj. mazowieckie

The first mention of the village dates from 1155. In 1827 the village had 50 houses and 465 residents. In 1884, the village had 31 houses and 626 morga in area. The Dutch colonists (several families) settled in the village at the beginning of the 19th century, by purchasing land from Poles. Initially, Łomna was a linear village located on the southern side of Vistula by the old Warsaw-Nowy Dwór Mazowiecki road.

The cultural landscape has been transformed. The homesteads have modern buildings located tightly on both sides of the street on an embankment that stretches along the river. Remains of traditional landscape (ponds and drainage canals, planted vegetation) are detectable on the meadows and pastures, which are situated lower towards the Vistula (in northern direction).
