In its construction, neither wood nor plaster were employed, the whole being built of stone bound together by iron bars.

La Force came under attack by violent mobs on 3 September 1792, and the four following days: one hundred and sixty prisoners, among whom were three priests and the Princesse de Lamballe, were massacred there.

[6] The prisoners slept in large and well ventilated chambers, and the boys each had a small apartment which contained a single bed.

[6] There was a department for the sick, a bathing-room, a parlor, and an advocate's room, where the prisoners could hold conversations with their legal defenders.

[6] The two prisons of La Force were demolished in 1845, and the only remaining part is a section of wall adjoining the City of Paris Historical Library.
