The Royal Atheneum of Bouillon

This imposing structure was built in 1768–1769 under architect Chauchet. The design is by renowned 18th-century architect Laurent-Benoît Dewez, who also redesigned the Abbey of Orval. Its original function was a hospice for poor children, the elderly, and the sick or wounded.

The idea for a hospice was approved in 1727 by Duke Emmanuel-Théodose de la Tour d'Auvergne but only realized 40 years later due to funding issues.

In 1848, the building also housed the Augustinian College for boys (est. 1635), which had to move from its previous site to make way for the Saints-Pierre-et-Paul Church. By 1855, the college fully occupied the building, and the hospice relocated to a former barracks (now gone).

Since then, the building has served as a school. It developed a strong reputation, attracting Flemish students who came to learn French. It also employed notable teachers and artists, including:

Poet André Drumaux (father of painter Angelina Drumaux)

Poet Louis Boumal

Painter Guillaume Edeline

Gym teacher Octave Blondeau, a WWI veteran

Painter André Rosbach, father of Bouillon’s mayor (1879–1895)
