Established by a decree of Marshall Józef Piłsudski in 1920, the Polish Army Museum has, for over a century, preserved a unique collection exceeding 300,000 exhibits. Until now, it lacked a dedicated headquarters to showcase its treasures. Today, after more than a century, the museum unveils its modern home, complete with a permanent exhibition and space for temporary exhibits and cultural events. The design of the new building is credited to WXCA Architectural Design Studio.
