Rosenfeld became a possession of the County, later Duchy, of Württemberg, which made the town the seat of its own district [de].

Rosenfeld underwent a period of growth after World War II, beginning in the 1950s with new housing to the east of the town, and continuing into the 1980s with more residential, commercial, and industrial areas.

[2] The township (Stadt) of Rosenfeld is located politically in the Zollernalbkreis district of Baden-Württemberg and physically in the Little Heuberg [de], part of the Swabian Jura.

[2] Rosenfeld's municipal coat of arms displays a five-petaled, white rose with gold seeds and green sepals on a field of red.

This pattern, in use by the town of Rosenfeld since 1372, was approved for official use by the Zollernalb district office on 11 May 1976.
