The museum's prime originality lies in its location, as its collections are housed in vaulted cellars dating from the 18th century. The visitor is thus taken back to the sole vestiges of the neo-classical buildings elected on plans by the architect Laurent-Benoît Dewez, which then served as the foundation when Orval was reconstructed in the beginning of the 20th century.

The 18th century's abbey cellars

The commemoration of the 900th anniversary of the founding of Orval was the initiative for setting up the museum in 1970. Most of the archeological objects were discovered during excavations of the church and medieval cloister carried out by Christian Grégoire and François Bourgeois, beginning in 1965. The paintings and liturgical objects were donated by private individuals.
The presentation is structured around five themes :

  1. monastic spaces and work,
  2. through the centuries,
  3. art and faith,
  4. figures of monasticism,
  5. contemporary creativity.

The architectural history of the Abbey is celebrated through several mock-ups, one of which reconstitutes the state of the monastery right before it was destroyed during the Revolution in 1793. At that time, there were two buildings next to each other: the old, medieval Abbey, and the new complex built by Laurent Benoît Dewez.
Stone remnants from various periods recount the various architectural styles from pre-Roman capitals to Baroque cherubs.
Typical Cistercian elements remain: tiles, wooden piping work, and above all, an acoustic pot, a rare peace found in one of the walls of the church's choir. It attests to the care that 12th century Cistercian monks took for the acoustics of their chants.

The iron and steel industry section comprises a fine collection of fireplace cast iron plates made in Orval forges. There are also art ironwork pieces and various kitchen utensils, all in cast iron. This part of the museum is intentionally more educational, featuring the place of the blast furnace, ore samples, etc.

The religious art section boasts the finest pieces from the art deco period, when monastic life resumed in Orval as of 1926. Some older items are also on display, in particular a splendid abbey crosier volute, a goldsmithing work by Friar Arman Robin, an 18th century monk.

A number of personalities emerge from the works on display :

  • Friar Abraham Gilson and his 18th century paintings,
  • Friar Antoine Perrin and his collection of clinical observations,
  • and finally the figure of Dom Marie Albert Van der Cruyssen, the abbot who rebuilt Orval.

Following a tour of thirty to sixty minutes, the visit continues with a temporary exhibit, and then reaches the Oratory of the Word, which offers space for meditation.


Next to the garden of medicinal plants, a building recreates the dispensary as it was in the 18th century, during the time of Friar Antoine Perrin, chemist. Orval was famous for its potions, especially its "eau d'arquebusade" or 'musket-shot water,' a vulnerary for gunshot wounds. The collection features a series of objects used for preparing medicines: crusher, tablet container, ornamented and figurative balance; but also for healthcare: leech syringe; plus a fine collection of earthenware for keeping herbs.
