Before the Renaissance palace was reopened, many works from the collections of MUDO – Musée de l'Oise or fortuitously discovered during the work were restored. Here are three examples.

Murals in the Couture Room

In one of the old courtrooms, the restoration work on the first floor brought to light murals dating from the late 18th century. An inspection report on the episcopal palace dating from 1793 and kept in the departmental archives mentions the large room and its "high ceiling with corniche, all painted in oils as faux marble with trophies". This Louis XVI décor was discovered to be fairly well preserved under its coatings.

La Vénus sortant des eaux

This large sandstone slab representing the birth of Venus was made in the late 19th century by Boulenger Frères in Auneuil based on a drawing by Joseph Félon. This Venus, very dirty and damaged due to its long exposure outdoors before it arrived at the museum, was restored by Sandrine Coignard. You can find this work along the 19th century tour route on the first floor of the Renaissance palace.
