The Ministère de la Culture's notice

Le donjon roman de Clermont est, malgré les nombreuses modifications qu'il a subi, l'un des plus anciens, des plus grands et des mieux conservés de Picardie. Edifié au 11e ou au 12e siècle, par un comte de Clermont, il fut rattaché à plusieurs reprises au domaine royal avant de demeurer dans la maison des Bourbon. Le donjon fut transformé en résidence par la princesse d'Harcourt, en 1703, après le déclassement de la ville comme place forte, ce qui entraîna de profondes modifications dans cette architecture défensive. Il fut en 1805 utilisé comme maison d'arrêt et de correction, puis en 1826, comme maison centrale de détention et enfin en école pour jeunes délinquants.

The Romanesque keep of Clermont is, despite the numerous modifications it has undergone, one of the oldest, largest and best preserved in Picardy. Built in the 11th or 12th century by a Count of Clermont, it was attached on several occasions to the royal domain before remaining in the house of Bourbon. The keep was transformed into a residence by the Princess of Harcourt in 1703, after the declassification of the town as a stronghold, which led to profound modifications in this defensive architecture. It was used in 1805 as a prison and house of correction, then in 1826 as a central detention facility and finally as a school for young delinquents.
