Seltso (Russian: сельцо; Polish: siołko) was a type of rural locality in the Polish–Lithuanian Commonwealth and the Russian Empire.
In the Polish–Lithuanian Commonwealth, the term referred to a small standalone khutor (hamlet), which often served as a unit into which a volost was subdivided.
[1] On the territory of Russia proper, this type of settlement was most common in Smolensk lands.
[1] The population of a typical seltso tended to be quite small, often limited to one or several families, or sometimes even just one person.
[1] In the later periods, the term was used to refer to a peasant settlement without a church around a landowner's estate.
