Gothic-style Catholic chapel (13th century).
The hamlet of Herbais, along with the chapel, the Jonet farm, and the old castle located south of the chapel and destroyed at the end of the 19th century, formed a seigneurial entity in the hands of the Herbais family.
The Sainte-Catherine Chapel is a building dating from the early second third of the 13th century: a priest is mentioned there as early as 1263.
According to some authors, the chapel was built on the model of the Saint-Médard church in Jodoigne. The nave was considerably remodeled in the 18th century: the old door, located to the north, was replaced by one pierced into the western facade, and the Gothic windows were replaced in 1767 with classical-style ones.
A restoration completed in 1971 restored the building to its supposed original state by recreating the pointed arch windows (gothic style) based on remains remaining on the site.
The three-sided apse is adorned, beneath its axial window, with the funerary monument of Denis Zualart (died 1576), Waulthier Scieve (died 1578), and Jehenne (Jeanne) Zualart, daughter of Denis and wife of Waulthier, who died in 1580.
The monument consists of a bas-relief depicting three figures kneeling at the foot of the cross, surmounted by a coat of arms consisting of a shield, a helmet, mantling, and a crest.
