Up until 2012, the Szołayski residence (15C-17C) was home to the museum devoted to Stanislaw Wyspiański (1869-1907), a key figure of the Young Poland movement, a local variant of Art nouveau. The premises have been treated to a facelift and now stage temporary exhibitions. A few canvases by Wyspiański are still visible, while others are undergoing restoration or are exhibited in the National Museum of Warsaw.
