Museum presents the history of the Castle and memorabilia from Ujazdów Hospital.
In 1994 the Association of Creators of the Castle and Military Hospital at Ujazdów was formed, and they created this Museum, which presents the history of the Castle. The collection features views of the castle, documenting its changes and purposes, and archival photos and memorabilia from Ujazdowski Hospital. Portraits of the owners of the castle and a cornerstone dated September 16, 1624 are also valuable exhibits shown here.
