The main goal of the Museum is to collect, store, research and share manuscripts, objects, publications and research materials related to the life and work of Stefan Żeromski.

Thanks to the foundation act and the will of Oktawia Żeromska, since its begging, the Nałęczów Museum collections were characterised by diversity and wealth. They include: furniture, items, everyday objects, personal souvenirs, first editions of the author’s works and works of art belonging to Żeromski and his family.

The Museum owns a rich collection of photographs, letters and documents related to the author of Homeless People. One should note the collection of correspondence (letters and postcards) of Stefan, Oktawia and their son Adam, as well as the iconographic materials, which include, among others, family photographs, portrait and landscape drawings made by Oktawia Żeromska, artworks by Adam Żeromski, projects, sketches and drawings by Jan Koszczyc-Witkiewicz (husband of Henryka Radkiewiczówna, step-daughter of Stefan Żeromski).

An important part of the collection is made of documents regarding the activities of the “Light” Educational Association, archives related to the design and creation of Nałęczów orphanage (today’s Adam Żeromski Orphanage, headquarters of the Bolesław Prus Museum), photographs and documents referring to Nałęczów’s history in Żeromski’s times, holiday prints, collection of journals from the era.
