This unique Queen Anne style playhouse was built in 1885 for five year old Lucy J. Haskell, daughter of Dr. William A. and Florence Hayner Haskell. It is believed Lucy's grandfather, John E. Hayner, commissioned prominent local architect, Lucas J. Pfeiffenberger, to design the playhouse. In 1889, at age nine, Lucy died of diphtheria. After Florence Haskell's death in 1932, the Haskell family gave the estate to the City of Alton for educational and recreational purposes. The playhouse was to be retained in memory of Lucy J. Haskell, designated a National Register Historic Landmark in 1974.
