ENThe structural peculiarities of the Merkys valley, the structural position of the settlings in the valley and their distribution into farmsteads (separate structural elements of the valley and the settling level of structural segments) are discussed. The majority of settlements in the Merkys valley are situated on the right bank of the river, where the farming conditions are more favourable. As the biggest part of this river valley is formed in a sandy plain of various limnoglacial levels with unfavourable conditions for intense farming, the majority of the settlements here are small, dispersive villages. On the riverhead, where the slope of the Merkys is narrow and of not a complex structure, the majority of settlements are situated in the slope of the valley, while on the lower reaches of the river where the valley of the Merkys is wide and complex, the majority of settlements are situated in the I, II terases, in accordance with their position to the river bed.
