Czerwieńsk [ˈt͡ʂɛrvʲɛɲsk] (German: Rothenburg an der Oder) is a town in Zielona Góra County, Lubusz Voivodeship, in western Poland, with 3,900 inhabitants as of December 2021.

[1] Czerwieńsk is a railroad junction, where the Wrocław – Zielona Góra – Szczecin connection meets the line to Poznań.

Around 1550 the von Rothenburg family from Nettkowe (Nietków) built a small hunting manor some 5 kilometres from their ancestral home.

While conveniently located at the crossing of important trading routes, the village's growth was halted by the devastating Thirty Years' War.

It served both local residents and the Protestant inhabitants of the nearby city of Zielona Góra, then part of the Bohemian (Czech) Kingdom ruled by the Roman Catholic House of Habsburg.

In 1736 Alexander Rudolf von Rothenburg was knighted by king Frederick William I of Prussia and received the title of a Count.

The family retained control of large parts of the town and its surrounding even after the abolition of feudal ownership in Prussia.
