The article presents a set of sources connected with the Trzciniec culture settlement discovered in site 2 in Jeroniki, Choroszcz dis., Podlaskie Voivodeship During the research a very inspiring collection of materials associated with settlement was documented 29 immovable structures, plentiful pottery and flint material. An analysis of source dispersion allows for attempting a reconstruction of spatial organization and settlement structure during the older bronze epoch. Documented immovable structures constituted three relatively distinctive clusters which could be interpreted as homesteads and overlapping the spatial location of discovered pottery fragments. On the basis of a multi-aspect analysis of movable sources (primarily ceramic) the complex from Jeroniki should be associated with “classical” and/or “early-classical” stage of development Podlasie–Mazovia groups of the TC. They were also accompanied by “eastern” elements, as well as certain stylistic archaisms associated with the late stages of development of the Mierzanowice culture. One should, however, bear in mind the possibility of different dynamics in the development processes of the TC community in the north-eastern Poland. Tracking it would require studies based primarily on results of absolute dating. In this light, the presented materials could contribute to further analyses.
