'ironworks city'; Lower Sorbian: Pśibrjog) is a town in the Oder-Spree district of the state of Brandenburg, in eastern Germany, on the border with Poland.

[6] Later on, it passed to the Kingdom of Bohemia, and Charles IV bought the town from the Cistercians of Neuzelle and allowed the construction of a bridge over the Oder to create a new trade route to Poland.

[7][8][9] The present-day town was founded as a socialist model city in 1950 following a decision by the East German Socialist Unity Party (SED), alongside a new steel mill combine located west of the historic town of Fürstenberg (Oder).

[10] A few years before the new town was established, a bridge over the Oder river had been constructed, the earlier one having been destroyed by retreating Wehrmacht forces in February 1945, near the end of World War II.

[12] The first design for the new residential quarter was developed by the modernist and Bauhaus architect, Franz Ehrlich, in August 1950.

His modernist plan, which laid out a dispersed town landscape along functional lines, was rejected by the Ministry for Reconstruction.
