The Museum of the Sochaczew Land and the Battle of the Bzura, located in the classicist town hall building from the 1830s in Sochaczew, plays a significant role in preserving local history and culture. The town hall, which served as the command center for the city's defense during the September Campaign of 1939, has been the museum's home since 1977, when it gained the status of a state cultural institution. The initiative to collect exhibits began in the 1970s under the Association of Lovers of the Sochaczew Land, and in 2015, Paweł Rozdżestwieński became the museum's director. Since 2022, the position has been held by Dr. Michał Górny. The museum boasts rich collections, featuring permanent exhibitions such as "Battlefield 1939–1945," which displays artifacts from World War II, including weapons, uniforms, and memorabilia of famous commanders. Another important exhibition is "Nad Bzurą bez zmian" (Along the Bzura Unchanged), focusing on the battles of the Bzura and Rawka between the Prussian and Russian armies from 1914 to 1915. The museum also showcases archaeological finds from the region, spanning from prehistoric times to the Middle Ages. The outdoor exhibition of Polish military equipment includes unique items, such as a 1939 engineer pontoon and a T-34/85 tank. The museum is open from Tuesday to Sunday, from 10:00 a.m. to 4:00 p.m., and is closed on Mondays. It serves as an important center for culture and regional education, also offering temporary exhibitions related to local themes, religion, and folk art.
