Trojanka (river)

It broadens into lakes at several places, and is joined by a number of smaller streams along its length.

The stream then continues north-westwards, flowing out of the Puszcza Zielonka Landscape Park, and turns sharply southwards at the settlement of Brody south of Wojnowo.

It flows through Trojanowo and Przebędowo (where it again forms a small lake), before running along the western side of the town of Murowana Goślina.

At a point south-west of the older part of the town (but north of the newer Zielone Wzgórza estate) it again turns north-west, flowing into another lake at Raduszyn, and from there to the village of Mściszewo.

There was formerly a village called Goślinka (or Mała Goślina—"Little Goślina") close to this point, but this is now part of Mściszewo.
