This article presents some cultural, historical and linguistic insights on the names of the Szczutowskie and Urszulewskie Lakes, both situated in the historical Dobrzyńskie Lakeland, today on the border between the Mazovian and Kuyavian-Pomeranian Voivodeships (the historical border between Polish and Prussian-Teutonic states). The author also takes into account the description of the local place and terrain names, showing a common relation with the natural landscape, in which the two lakes are immersed.
