There was no fixed rent for the apartments of the Press-Yard and Castle. Rather, the Keeper applied a sliding scale, depending upon the Degree of the personage imprisoned. A Duke—let us say, a rebel Scottish lord—would be expected to pay a premium of five hundred guineas upon admission to the gaol, simply to escape from the Common-Side and Master-Side. Having got over that hurdle he would, each week, then have to pay the gaoler about a mark, or thirteen shillings and change, for the privilege of staying in a room such as this one.
