The originality and interest of the collections of the Hospital Notre-Dame à la Rose lies in their variety and quality. Indeed, they illustrate many areas of the history of art and science. Moreover, they are preserved in situ and contribute very largely to recreate an atmosphere, peculiar to this place where time seems to have stopped. Many links can be highlighted between the objects presented today to visitors and the daily life or major events experienced by those who made and wrote the history of Notre-Dame à la Rose .
The art collections contain several thousand pieces. They include Gothic and Renaissance furniture as well as Regency or Baroque woodwork. The credenzas and the Gothic benches are unique in Belgium.
