Łowicz [ˈwɔvʲit͡ʂ] is a town in central Poland with 27,436 inhabitants (2021). It is situated in the Łódź Voivodeship. Together with a nearby station of Bednary, Łowicz is a major rail junction of central Poland, where the line from Warsaw splits into two directions—towards Poznań, and Łódź. Also, the station Łowicz Main is connected through a secondary-importance line with Skierniewice.
Łowicz was a residence of Polish primates in the Polish–Lithuanian Commonwealth. They served as regents when the town became a temporary "capital" of Poland during the interregnum. As a result, Łowicz has its own bishop and a Cathedral Basilica in spite of its considerably small size. The Cathedral Basilica is designated a Historic Monument of Poland, and the ruins of a former bishop's castle can be found on the outskirts of town. Also, the town was at the centre of the largest battle of the German invasion of Poland, the Battle of the Bzura River, in the opening campaign of World War II.
