Mr and Mrs Maria and Marian Dąbrowski moved into flat no. 31 in the tenement house at 40 Polna Street (current address 1 m. 13 Progi Street) in August 1917.

The three-room, one-hundred-metre flat was, by the standards of the time, not very exquisite accommodation for a young, childless intellectual couple. On the outskirts of Warsaw (further away was Pole Mokotowskie, hence the name of Polna Street), in an annexe on the second floor.

Maria Dąbrowska lived in this flat for 37 years, and most of her outstanding writing, including the novel Noce i dnie (Nights and Days), was written here. She also located the plot of some of her works here. Despite moving out in 1954, she often returned to Polna Street with her thoughts, which she expressed in her Dziennik [Diaries].

The Maria Dąbrowska Museum at 40 Polna Street was established in 1984 through the efforts of the writer's friends and neighbours. Furniture, memorabilia of the writer, some manuscripts and photographs, paintings painted by her hand and a huge book collection were returned to flat no. 31. As the tenement house was not destroyed during the Second World War and is one of the few landmarks in left-bank Warsaw, the beautiful cookers, stuccoed ceilings, pre-war floor, shutters and doors have survived in the flat.

The Museum presents the writer's literary and journalistic legacy, her artwork and personal memorabilia, including her extensive book collection. The profiles of Marian Dąbrowski and Stanisław Stempowski are also recalled. The Museum hosts museum lessons, literary evenings, lectures, readings, chamber concerts, theatre performances as well as book promotions and meetings with people of culture,
