The Józef Piłsudski Museum in Sulejówek, established under an agreement signed on November 10, 2008, by Jadwiga Jaraczewska and the Minister of Culture Bogdan Zdrojewski, is an institution dedicated to commemorating the life and work of Marshal Piłsudski. The museum consists of two main parts: the historical section, which includes the "Milusin" manor, the Piłsudski family's first home in Sulejówek known as the "Drewniak" (Wooden House), and the "Bzów" villa, as well as a modern museum and educational building that combines exhibition and educational functions. The construction of the new facility was completed in 2020, and the museum was officially opened on August 14 to mark the 100th anniversary of the Battle of Warsaw. The permanent exhibition presents Piłsudski's life through five chronological galleries: Ziuk, Wiktor, Komendant, Naczelnik, and Marszałek, as well as the Symbol gallery, which highlights the memory of his legacy and the mythology surrounding his figure. The museum continues the legacy of an earlier museum in Warsaw, which operated until 1939. In addition to historical collections, the museum features works of art, such as urban landscapes of Vilnius by Ignacy Pinkas and the sculpture "Szaman" by Julia Stabrowska. It is also worth noting that before the war, the "Milusin" manor housed a kindergarten, which is an interesting aspect of its history. Since its establishment, the museum has been directed by Krzysztof Jaraczewski, Robert Supeł, and currently Robert Andrzejczyk, demonstrating the continuity of efforts to commemorate one of the key figures in Polish history.
