The site is described in archive documents, along with the animal yard:

"(...) we see Brother Amable, with a few children, busy inside the dwellings, and also the farmyard filled with rabbits, pigs, goats, turtles, pigeons, ducks, chickens, turkeys (…)"

(Extract from a letter written by Father Limbour following a visit to the prison)
