In the original version, the cell had only a small door leading to an individual courtyard, and from there one could get into a common prison yard. Later, the windows were replaced with low double doors with bars on the inside and a sliding oak door on the outside. The lattice held the prisoner, and the oak door was made for soundproofing, and did not allow to communicate with a neighbor on the other side of the corridor.
