Prior to 1945, Gubin was part of Guben in Germany. In 1945 the Oder-Neisse line was chosen as the new German-Polish border at the Potsdam Conference. This meant that Guben would be split between the two countries, with the eastern portion of the city, including the historic centre, becoming Polish Gubin.
The central part of Gubin was seriously damaged at the end of World War II, with the historic town hall and church being burnt out. While the town hall has since been restored, the parish church is today a stabilised ruin.
A large army garrison was based in Gubin from 1951-2002, including the 5th Infantry Division, which evolved into the 5th Saxon Tank Division in 1956. The garrison was closed in 2002 following restructuring.
Gubin lies on the no. 32 road that works as an orbital road for Gubin, which starts at the border crossing with Guben to Krosno Odrzańskie and Zielona Góra and comes to the no. 5 road that links to Poznań. Gubin has also a railway border crossing.
Gubin has a land mass of 20.68 km² of which 61% is used for agricultural purposes and 5% is used for forest uses.
The city takes up 1.49% of the area of the Krosno Odrzańskie County
In Gubin, all of the schools to date are state-run by the Ministry of Education in Poland.
